Re: Munt Reloaded - Development

Hi NewRisingSun, That's an interesting one, thanks! The intention of the code does seem to match the behaviour you describe: releasing the hold pedal (controller 64 = 0) releases all sustaining notes I have a brief holiday starting today, so when I get a chance I'll try to track down why it doesn't …

Re: Munt Reloaded - Development

Yes, we've had plans for this for some time. The closest we have right now is tools to: - generate thousands of combinations of timbre parameters, MIDI notes, velocity, etc. - send the MIDI to the real CM-32 and capture the digital output - send the same MIDI commands to Munt and record its output ( …

Re: Munt Reloaded - Development

Still on board but, realistically, probably unable to do any Munt work for another 4 weeks or so. In the mean time, sergm is doing a fantastic job on the new GUI application, so good things are coming. You can read a bit about the DAC capture method here: http://www.vogons.org/viewtopic.php?t=10850& …

Re: Munt Reloaded - Development

Thanks Cloudschatze, that's really useful information. I was a bit mystified when everything I tried to reproduce the reported lightning bug gave (more or less) identical results on my CM-32L and Munt. Are you sure that the differences are due to different LA32 revisions rather than firmware bugs?

Re: Munt Reloaded - Development

Hi OmerMor, Sergey had a holiday and I had some distractions, but we're getting back on track (coincidentally, we just exchanged some emails about this a few minutes ago). I've been holding things up a bit wrt. mt32emu-qt - I need to flesh out some architectural stuff. On the positive side, we're …

Re: Munt Reloaded - Development

Hi NewRisingSun, I'm glad to hear the latest Munt version is working out so well for you. I'm a little confused regarding request (2) - mt32emu-smf2wav by default waits until the emulator output has settled to zero. Which version are you using? A command-line argument for specifying the number of …

Re: Munt Reloaded - Development

Hi OmerMor, Regarding the die scans: Apparently the guys involved haven't given up or forgotten about it - I still get occasional "in progress" updates from them. SergM did some incredible analysis work on the waveform generation that allowed us to get very close to what the LA-32 is doing. Die …

Re: Munt Reloaded - Development

According to information from Mok, the MT-32 has these controllers: Modulation depth Expression Pitch bend Pitch bender range* Volume* Pan pot* Hold** * Part of the "patch", so changed to the value in the new patch on program change. ** Explicitly reset on program change (this is the bit we were …

Re: Munt Reloaded - Development

Due to androidi's constant nagging that reverb was too loud, I looked into it and noticed that there are different resistors on the reverb channels than the non-reverb/dry channels. I've reduced the default reverb gain to what I think is appropriate based on the schematic, though we'll double-check …

Re: Munt Reloaded - Development

I pushed a change removing emulation of that bug, since I was unable to reproduce it on my CM-32L. I couldn't find anything we're doing that could cause the bug to be hit when it wouldn't be on the real thing. Mok did double-check to make sure that he'd accurately documented the bug at the time, so …

Re: Munt Reloaded - Development

worst719, thank you very much for pointing this out. I have some uncommitted sysex read code that also includes support for the handshaking sysex method. I wasn't aware that any games used this method, so I wasn't planning to commit it until we had complete sysex read support. It's very good to know …

Re: Munt Reloaded - Development

The cause is in Bit16u TVP::nextPitch() timeElapsed = timeElapsed & 0x00FFFFFF; After 30 sec of sustaining timeElapsed gets value of 2^24 and goes around ... If I make the mask wider, it sounds OK but I can't say whether it would be some side effects. Those tvX modules aren't so clear.... and I'd …
