Hello list,

I am working on a Max patch that uses csound~ as the synth engine.
I would like to send values of 1 from Max to start an envelope's attack and decay phase and values of 0 to start the release phase.
I have looked through all the envelopes, but I don't seem to find any of them that might work with a trigger that is not MIDI.
any suggestions?
also, if the instrument is polyphonic, would there be a way to make the trigger act independently on each note, rather than being applied to the amplitude of the whole instrument?

hope this is clear.
I'd really appreciate your help.

Andreas

It's possible, you could try to use on instrument to control another, with "event" / "turnoff2"

You could send csound~ event messages (beginning with e) that will be your 'notes' and use an envelope like envlpx, sending in these score events the 'trigger' and time values for your envelope.

May not be exactly what you are trying to accomplish, but...

Hope this helps

Hi Andreas,

One possibility that comes to mind is to use held notes (negative p3)
and code the instrument using one of the envelopes with release
segments (i.e. transegr, linsegr, expegr).  These envelopes will
generate up until the sustain and hold on that, then when the note is
turned of, the release time is processed separately from the note
duration.

As for individual attacks per note, you can do that by using extra
pfields.  It may pay off then to pass a note event into csound~
instead of passing a k-rate value.  So, instead of 1/0, using score
events like "i 1.1 0 -1 3 4 5" and "i 1.1 0 1 3 4 5". Doing this,
you'll have to use the skip init flags in opcodes and perhaps use
fractional notes to track individual instances of note to turn on/off.

they all seem like very valuable possibilities.
I'll try them all and see what fits better.
thanks you all!

hello list,

I am building an iPad conrtolled, Max patch that using Csound as a synthesizer.
I am triggering MIDI notes by touching different spots of the iPad screen, and I would like to have "independent pitch bend", as in, by sliding the finger associated with the note, only that note glides. each note is independently controlled by its finger, rather than by a generig pitch bend.
do you have any idea on how to communicate that to Csound?
as in, what opcode, if any, would allow me to send "poly" pitch-bend messages?

I always apprechiate your help, or even just reading the list. such a source of inspiration.

Andreas

hello,

I think pitchbend is valid for all notes in specified midi channel,.If you 
don't have too many notes playing or you can map them areound in some clever 
way so that you reserve some channels for notes that you want to bend and send 
there nothing else in the same time.

or otherwise you should read the pitch bend amount with pchbend opcode and 
apply it to your audio signal for example with pvscale (see  
http://csound.1045644.n5.nabble.com/Pitch-shift-td1119743.html )

so you are out of  the restricted midi area to the unlimited ocean of csound 
:)

if it helps...

The multitouchXY example in the iOS and Android SDK's do essentially
this, where each note has it's own pitch controlled by finger.
Essentially, the control signals from the fingers mapped to channels,
each with it's own id, something like "pitch.1", "pitch.2", "amp.1",
"amp.2".  Each note that got start had an ID associated with it, and
the code inside would use the ID to read from a specific channel.

You can find the code in either of the SDK's, or view online here for iOS:

http://csound.git.sourceforge.net/git/gitweb.cgi?p=csound/csound5.git;a=tree;f=iOS/Csound+iOS+Examples/Csound+iOS+Examples/ViewControllers/MultiTouchXY;h=e5de2b3746b69c5b3bdffd715932fb5068afe3cb;hb=HEAD

In the CSD, you'll find:

S_xName sprintf "touch.%d.x", i_instanceNum
S_yName sprintf "touch.%d.y", i_instanceNum

Good luck!
