Subject	[Csnd] Score generation
	Hi folks. I've written two csound score generators. Mother uses Markov processes and Automata uses Stephen Wolfram's automata rules to generate score events. For those with C compilers, all the source code is part of the package, otherwise it's a Mac only affair for the time being I'm afraid. The manual is in Mac MS Word 5 format. I hope to have an HTML manual completed in the next few days. You can get it from: Cheers Arne -- To unsubscribe, send email to csound-unsubscribe@lists.bath.ac.uk Received: from shaun.maths.bath.ac.uk by omphalos.maths.Bath.AC.UK id aa14778; 4 Nov 99 20:17 GMT Received: from [138.38.32.81] (helo=mercury.bath.ac.uk ident=qmailr) by shaun.maths.bath.ac.uk with smtp (Exim 2.12 #1) id 11jTJn-0007hS-00 for j.p.ffitch@maths.bath.ac.uk; Thu, 4 Nov 1999 20:17:11 +0000 Received: (qmail 29697 invoked from network); 4 Nov 1999 20:00:55 -0000 Received: from amos.bath.ac.uk (qmailr@138.38.32.36) by mercury.bath.ac.uk with SMTP; 4 Nov 1999 20:00:55 -0000 Received: (qmail 12578 invoked by uid 1457); 4 Nov 1999 19:59:20 -0000 Mailing-List: contact csound-help@lists.bath.ac.uk; run by ezmlm Precedence: bulk X-Mailing-List: csound Delivered-To: mailing list csound@lists.bath.ac.uk Received: (qmail 12564 invoked from network); 4 Nov 1999 19:59:20 -0000 Received: from pat.bath.ac.uk (138.38.32.2) by amos.bath.ac.uk with SMTP; 4 Nov 1999 19:59:20 -0000 Received: (qmail 24255 invoked from network); 4 Nov 1999 19:59:19 -0000 Received: from hermes.ex.ac.uk (HELO exeter.ac.uk) (144.173.6.14) by pat.bath.ac.uk with SMTP; 4 Nov 1999 19:59:19 -0000 Received: from noether [144.173.8.10] by hermes via SMTP (TAA1417917); Thu, 4 Nov 1999 19:59:18 GMT From: kim@anechoicmedia.com Received: from exeter.ac.uk by maths.ex.ac.uk; Thu, 4 Nov 1999 19:59:17 GMT Received: from [209.157.7.66] by hermes via ESMTP (TAA1464410); Thu, 4 Nov 1999 19:59:16 GMT Received: from kim-1.staccatosys.com (KIM-1 [192.168.1.156]) by mail.staccatosys.com with SMTP (Microsoft Exchange Internet Mail Service Version 5.5.2448.0) id 4WKCPFSG; Thu, 4 Nov 1999 11:58:45 -0800 Message-Id: <3.0.5.32.19991104115850.0095f920@pop.sirius.com> X-Sender: anechoic@pop.sirius.com X-Mailer: QUALCOMM Windows Eudora Light Version 3.0.5 (32) Date: Thu, 04 Nov 1999 11:58:50 -0800 To: csound@maths.ex.ac.uk Mime-Version: 1.0 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable Subject: [Csnd] SynthCore SDK FOR IMMEDIATE RELEASE 11/1/99 Mountain View, Ca- Staccato Systems=99, Inc., a leading developer of interactive audio technologies, today announced the SynthCore Software Development Kit beta program for game audio developers. The SynthCore SDK is a set of APIs, programs and content that gives game audio sound designers and programmers the ability to create and deliver interactive audio uniquely controlled by the game physics, environment and end user input.=20 The SDK consists of the SynthCore audio rendering engine, as well as a preset editor and comprehensive audio content. The SynthCore engine currently performs physical modeling of sound as well as wavetable, DLS and algorithmic audio synthesis, with several new audio technologies in development.

Even a slow machine should be fast enough for MIDI. So it sounds like there's some scheduling problem somewhere. Maybe the v_midi driver is buggy?

It worked fine. I decided to change AXCsound back from my hacked version of the Csound sources (shared library, re-entrant, etc.) to a plain old shell abain (runs good old consound or Winsound in a separate process). The reason? I didn't want to have to keep maintaining my code in synch with the "canonical" csound code. If the Csound community would like Csound to be a software component with usable hooks, amenable to use in different contexts such as Java, ActiveX, shared libraries, I've done half the work and have an idea how to do the rest, but I'm not willing to keep doing it over and over. I know that John ffitch is not an expert Windows programmer and does not have an up to date Windows development system, so perhaps the present situation is understandable, but it is not necessary. If the community desires to make Csound more usable the following steps can be taken: Csound changes from an executable program with a main() function, into a static library with various functions: sco and orc file readers, audio input, audio output, command input, score line input, midi event input, midi event output, console message output. This library is written ENTIRELY in lowest-common-denominator runtime-library-only C++. The code is re-entrant and multiply instantiable (several instances of Csound can run inside the same process or address space, at the same time). The API for Csound becomes: // C S O U N D // Copyright (c) 1999 by Michael Gogins. All rights reserved. // P U R P O S E // Declares a low-level interface for controlling Csound, // which is designed to be useful in as many different contexts as possible, // such as the JavaSound API, VST 2 plugins, Buzz machines, and others. // Therefore, Csound depends ONLY upon the builtin facilities of the ANSI C++ language; // the synthesizer is supposed to be COMPLETELY platform-independent. #ifndef Csound_h #define Csound_h #pragma warning(disable: 4786) #include #include // An abstract object for synchronizing access to objects // that are shared by different threads. class AbstractMonitor { public: virtual ~AbstractMonitor(){}; virtual void wait()=0; virtual void notifyAll()=0; virtual void enterMonitor()=0; virtual void exitMonitor()=0; }; class Csound { public: virtual ~Csound(){}; virtual long createKernel()=0; virtual void destroyKernel(Csound kernel)=0; virtual void loadPlugins()=0; virtual bool read(std::string xmlFile)=0; virtual bool start()=0; virtual bool pause()=0; virtual bool resume()=0; virtual bool stop()=0; virtual bool commandInputOpen(AbstractMonitor monitor)=0; virtual bool commandInputClose()=0; virtual bool commandInputIsOpen()=0; virtual void commandInputWrite(std::string command)=0; virtual bool midiInputOpen(AbstractMonitor monitor)=0; virtual bool midiInputClose()=0; virtual bool midiInputIsOpen()=0; virtual int midiInputWrite(signed char event, int size)=0; virtual bool midiOutputOpen(AbstractMonitor monitor)=0; virtual bool midiOutputClose()=0; virtual bool midiOutputIsOpen()=0; virtual int midiOutputRead(signed char buffer, int size)=0; virtual int getAudioSampleFramesPerSecond()=0; virtual bool setAudioSampleFramesPerSecond(int value)=0; virtual int getAudioSampleFramesPerControlSample()=0; virtual bool setAudioSampleFramesPerControlSample(int value)=0; virtual int getAudioInputChannelCount()=0; virtual bool setAudioInputChannelCount(int value)=0; virtual bool audioInputOpen(AbstractMonitor monitor)=0; virtual bool audioInputClose()=0; virtual bool audioInputIsOpen()=0; virtual int audioInputWrite(float audioInputBuffer, int count)=0; virtual int getAudioOutputChannelCount()=0; virtual bool setAudioOutputChannelCount(int value)=0; virtual bool audioOutputOpen(AbstractMonitor monitor)=0; virtual bool audioOutputClose()=0; virtual bool audioOutputIsOpen()=0; virtual int audioOutputRead(float audioOutputBuffer, int count)=0; }; #endif // Csound_h The AbstractMonitor thing is modeled on Java monitors and can be a proxy for them, but can be implemented in any operating system; it's what allows the Csound engine to synchronize input and output streams when running in a VST or ActiveX plugin. The csound executables, and specific implementations of AbstractMonitor, are written separately for each platform and contain all system calls for feeding data into and out of the Csound library calls. The Csound library also can easily be given an ActiveX and JavaSound interface with only the thinnest layer of glue, and the library is designed to make it as easy as possible to write VST or ActiveX plugins using Csound as an engine. I got line events and JavaSound MIDI input working using this approach, but my code was diverging so far from the canonical sources I had nightmares about what would happen to me if I tried to keep maintaining it. Making these changes not only would enable Csound to become all kinds of useful goodies, it would also make Csound itself much easier to maintain and develop further, because the "engine" would be identical on all platforms. Based on experience with AXCsound, I estimate that producing the "engine" library is about 2 months of part-time work for one person, and each platform's "consound" executable about 1 or 2 weeks of part-time work for one person. -----Original Message----- From: steve@cs.tu-berlin.de [mailto:steve@cs.tu-berlin.de]On Behalf Of Stefan Kersten Sent: Thursday, November 04, 1999 5:21 PM To: Paul Barton-Davis; Csound List Subject: Re: [Csnd] [CUD] line event problem BTW (1), I followed your really detailed description earlier on the list (thanks :), and it is no problem at all to work with the v_midi dev and OSS.

Those requirements are: * libsigc++ ported (true for most mainstream and semi-mainstream platforms) * C++ compiler that can handle namespaces, exceptions, and a few other minor modern features * pthreads (POSIX P.1003 standard) if your system has these, then implementing the required classes to port libmidi and libaudiohw should take about 1 hour each. currently, this is all only in CVS: no tarballs have been constructed, and it will be little while before they are. --p -- To unsubscribe, send email to csound-unsubscribe@lists.bath.ac.uk Received: from shaun.maths.bath.ac.uk by omphalos.maths.Bath.AC.UK id aa15755; 5 Nov 99 4:27 GMT Received: from [194.184.60.149] (helo=ax-nicb.axnet.it ident=root) by shaun.maths.bath.ac.uk with esmtp (Exim 2.12 #1) id 11jaxq-0007w8-00 for jpff@maths.bath.ac.uk; Fri, 5 Nov 1999 04:27:09 +0000 Received: (from nicb@localhost) by ax-nicb.axnet.it (8.8.7/8.8.7) id UAA03351; Thu, 4 Nov 1999 20:17:51 +0100 Date: Thu, 4 Nov 1999 20:17:51 +0100 (CET) From: Nicola Bernardini To: jpff@maths.bath.ac.uk cc: sbrandon@music.gla.ac.uk, csound@lists.bath.AC.UK Subject: Re: [Csnd] Win NT Problems take 2 In-Reply-To: <5137-Wed03Nov1999101324+0000-jpff@maths.bath.ac.uk> Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Yesterday, jpff@maths.bath.ac.uk mi scrisse cio` che segue: > Can i think aloud about your problems?

If anyone has an .orc/sco that reads in a file and changes its length or pitch, it would be greatly appreciated! (I've gotten to the point of analyzing a soundfile on my own, now i just need some hints on what to do next.) I am running windows 95 on a 200Mhz PII with 64 Mg of ram, CSound ver 3.58 Thanks in advance, Bob Dornberger bob@pantu-tanosimi.com -- To unsubscribe, send email to csound-unsubscribe@lists.bath.ac.uk Received: from shaun.maths.bath.ac.uk by omphalos.maths.Bath.AC.UK id aa16333; 5 Nov 99 10:25 GMT Received: from [138.38.32.81] (helo=mercury.bath.ac.uk ident=qmailr) by shaun.maths.bath.ac.uk with smtp (Exim 2.12 #1) id 11jgYQ-000875-00 for j.p.ffitch@maths.bath.ac.uk; Fri, 5 Nov 1999 10:25:10 +0000 Received: (qmail 17498 invoked from network); 5 Nov 1999 10:21:20 -0000 Received: from amos.bath.ac.uk (qmailr@138.38.32.36) by mercury.bath.ac.uk with SMTP; 5 Nov 1999 10:21:20 -0000 Received: (qmail 21544 invoked by uid 1457); 5 Nov 1999 10:19:41 -0000 Mailing-List: contact csound-help@lists.bath.ac.uk; run by ezmlm Precedence: bulk X-Mailing-List: csound Delivered-To: mailing list csound@lists.bath.ac.uk Received: (qmail 21538 invoked from network); 5 Nov 1999 10:19:41 -0000 Received: from pat.bath.ac.uk (138.38.32.2) by amos.bath.ac.uk with SMTP; 5 Nov 1999 10:19:41 -0000 Received: (qmail 26020 invoked from network); 5 Nov 1999 10:19:40 -0000 Received: from hermes.ex.ac.uk (HELO exeter.ac.uk) (144.173.6.14) by pat.bath.ac.uk with SMTP; 5 Nov 1999 10:19:40 -0000 Received: from noether [144.173.8.10] by hermes via SMTP (KAA1424596); Fri, 5 Nov 1999 10:19:39 GMT Received: from exeter.ac.uk by maths.ex.ac.uk; Fri, 5 Nov 1999 10:19:38 GMT Received: from mail21.svr.pol.co.uk [195.92.193.27] by hermes via ESMTP (KAA1401254); Fri, 5 Nov 1999 10:19:37 GMT Received: from modem-12.longnose-hawk.dialup.pol.co.uk ([62.137.40.12] helo=internetpc) by mail21.svr.pol.co.uk with smtp (Exim 2.12 #2) id 11jgSy-0002Re-00; Fri, 5 Nov 1999 10:19:34 +0000 Message-ID: <003b01bf2710$1293cf60$0c28893e@internetpc> From: richard bowers To: bob Cc: csound csound References: <01bf274d$1a5e0e80$1eee7ece@endxokep> Date: Thu, 4 Nov 1999 22:00:21 -0000 MIME-Version: 1.0 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: 7bit X-Priority: 3 X-MSMail-Priority: Normal X-Mailer: Microsoft Outlook Express 5.00.2314.1300 X-MimeOLE: Produced By Microsoft MimeOLE V5.00.2314.1300 Subject: Re: [Csnd] Phase Vocoder help Dear Bob, I hope this will help. This is the simplest kind of phase vocoder orchestra. I shall assume that the analysed audio segment is 5 seconds long, 44100 kHz, mono and the analysis has been named "sound.pva". The crucial thing is the passage of the pointer through time. Looking at the manual entry for the pvoc unit ar pvoc ktimpnt, kfmod, ifilcod ktimpnt is the k-rate pointer through the analysis file. You need to control the speed at which the analysis is being read. A simple way of doing this is using the line opcode as follows: ktimpnt line 0, p3, 5 This will read through the analysis file from start to finish (5 seconds) over duration p3 (specified in the score). In other words, if you give the value 10 to p3 in the score it will take 10 seconds to read through the 5 second file. That's timestretch. Conversely, the pitch can be modified using the kfmod parameter. This modifies the pitch by the specified ratio, which is also a krate variable. In other words if you make kfmod 2, the sound will be output an octave higher, 0.5 an octave lower and anything else for pitches other than the octave. We shall use p4 in the score for pitch transposition. So to implement this as a orchestra we get: ;********* sr=44100 kr=4410 ksmps=10 instr 1 ktimpnt line 0, p3, 1 asig pvoc ktimpnt, p4, "sound.pva" out asig endin ;******* The score may be something like: ;******* i1 0 5 1; normal output ie. 5 secs at normal pitch i1 5 10 1; normal pitch twice as long i1 15 5 .5; normal duration octave lower i1 20 2.5 .78 ; changed duration and changed pitch e ;********* Hope that helps, but remember...that's only the beginning. You don't have to limit yourself to uniform timestretch or pitch shifts. You can access the analysis arbitrarily to hack the sound up or whatever. Also, the related opcodes give you much more control such as accessing individual spectral components from the analysis or morphing between different analyses. Have fun.
