This looks very promising: Not sure what the dirty lo-fi engine means but this app has some very nice features which could make this FM-synth the most useful FM-App on the iPad.
Just came across software called MSX Synth – it’s not specifically for the CX5M but you can use it to play around with the internal Yamaha sound chip: http://paxangasoft.retroinvaders.com/msxsynth.htm
It’s very nice to see how Paxanga has used the graphic possibilities of the MSX1 to make an advanced interface for the PSG sound chip. You can see a video here how it works:
Paxanga soft claims it’s still in development but I think it’s worth a try already.
Amazing that I haven’t come across this MML player before: http://mmltalks.appspot.com/
I used to program songs in MML on the MSX (the Music Macro cartridge YRM-104 also makes use of this syntax).
The MML Player is based on Flash’ SiON engine which actually is able to emulate all the CX5M’s soundchips: https://sites.google.com/site/sioncenter/example
So a while ago I got a request from Paul Deco if I could put the .vog soundfiles back online. The CX5M shares the instrument-data structure with the FB-01 so they could be handy for FB-01 users too. I’ve zipped them here
Now, In the previous version of this site there was also a .VOG decoder. I’ve been working on that too so you can see what sounds are inside the .VOG files (typically 48 instruments per file). I have not made the file uploader for that decoder in this new CX5M site (a bit worried about security since the contact form is already spammed now and then) but you can browse through some instruments. You can click on the links below and see how the sound parameters are setup. WARNING: It’s a load of numeric stuff if you’re not into FM programming…
*update* – Midislav disk is downloadable here
It’s still running but after about 30 years it’s probably time to backup the floppies…
