Real-time audio synth!
I'm so excited, I just had to tell everyone! I started working on an audio
synthesizer that you can control in real-time with a MIDI keyboard! It uses
midi.ew (by Brent Hugh) and BassASIO (beta version) which I just recently
discovered. I made a wrapper for it, which seems to be working so far. What's
cool about ASIO is it has very low latency input and output. However, you can
only use it if your sound card supports ASIO (most high-quality or professional
ones do.)
I used the sine wave generating code from the "BASS Simple Synth" demo program
(that came with the Bass euphoria wrapper from Elliott Sales de Andrade) as a
test. The original program (using Bass) skips unless I set it to about 50ms
latency. But when using BassASIO instead, I believe my test program has only
about 5-10ms latency! You can actually hear the notes instantly when you play the
keys. Later, I may try making a real-time effects engine that can process
incoming audio - it would be cool to make a software guitar effects processor.
I'm assuming the latency would at least double when dealing with input and
output.
Just generating simple sine waves, it used about 60% of my CPU (Athlon64 3200+)
just to play 10 notes at a time. I don't know at this point how well it will
handle complex synthesis and effects.
Are there any musicians here that would be interested in this project?

No, FluidAE is not dead yet 
I will work on it some day...
