Dear Csounders,
I have been experimenting with Realtime MIDI input and Csound.  I had
posted to the group a couple months ago to get advice on the limitations
of Csound and whatever gear I was planning to buy.  Well, I have all my
gear.  A Roland GR30 guitar synth (with GK2A pickup) running into my
computer (IBM Aptiva Pentium II 300Mhz) via a MIDI to serial adaptor.

My problem is that I get about a 0.2 second lag time between my attack and
the output of the signal.  Just enough to be annoying.  I've tried a few
things.  I tried using Gabriel Maldonado's VMCI to see if my external
controller was the problem.  It's not...the delay is still there with
VMCI. I've tried a few scripts. Here is the simplest one I could think of:

orchestra===========

sr = 22050
kr = 441
ksmps = 50
nchnls = 1

instr 1
ipch pchmidi
a1 pluck 5000, cpspch(ipch), cpspch(ipch), 0, 1
out a1
endin

score=============

f0 600
e

I also have a much more complex script (which I'll share if anybody's
interested), and both give roughly the same 0.2 second delay so I'm not
sure how much more I could streamline my scripting.

I'm also pretty sure that my computer has enough horsepower, although I
could be wrong.

I don't know how to change my buffer sizes in the interface I use (WCShell
and RTSound 1.8.)

Can anybody with experience in this area offer insight into why I can't
get rid of my lag time?  Any help would be appreciated,  Thanks!

Try the latest Maldonado build - DirectCsound v.2. This version uses
DirectX to drastically reduce latency... quite playable on a 166Mhz
pentium!
