Hi, I'm Tolaemon the maker of the -hard plAYer- . I was checking the visits of the project's home, and found this forum. I've read all your posts and I think that all them are very interesting.
I haven't started to implement the MIDI functionality yet. In fact I'm trying to write a good specifications before starting programming it. The initial hardware is the one you can see in the web, and I'll work over this one for one year maybe, but I would like to make a new board revision with some improvements later. The most important improvements would be the possibility of adding up to 4 YMs, and an LMC-1992 similar audio IC to improve sound quality. Pehaps, I'will also offer an optional design with a slectable analog distortion, or another interesting analog effect, to allow the user play a bit with AY sounds.
The synthesizer will play the notes received through it's MIDI IN port, and the idea is to let the user use it as 3 monphonic patch synth, or as a single patch with 3 notes of polyphony synth. Adding more AY's would increase the polyphony of the synthesizer. The instruments characteristics ( envelope, wave type, effects etc.) would be deffined with a PC application and then saved in the SD card ( sorry I'dont have MAC) . The synthesizer should be able to read the instruments saved in the SD card and use them to play the notes.
The used processor has not enough RAM to play user defined samples, but It will be able to work with PCM generated square, sine, triangle and ramp waves ( at least this is the initial idea )
As all you, I spend most part of my "life-time" at work, and It's difficult to me find spare moments to dedicate to developing this project, but I'm there, trying to advance, and be sure that I'll keep you informed about the important advances on it.
Any constructive opinion or sugestion will be welcome!
