I always thought that the original MT-32s were more desirable because of the overflow? Something about certain sound effects not playing correctly on the later models where this has been fixed. You are talking about digital overflow, which is in DAC design. This fix is about MIDI messages overflow, …

Back in 90s, i had WD Paradise Bali32 pci video card. 1mb + 2 slots for EDO expansion. It was based on ARK1000PV

Here is the pc081.mid recorded via SC88 SPDIF: https://www.vogons.org/download/file.php?mode=view&id=157045 About E3 i tried record then realized that the default settings for square wave can be different on different devices (reverb, chorus, ADSR, etc), so the only way to be in equal conditions is …

I'll try to capture on Sunday, and there's no problem to record any note at any pitch. As a reference i think it is, no doubt, A4 which has clean 440Hz base.

any idea, which sound, etc is best to be captured? I mean we have all the sounds from the ROM, I posted SC-88 descrambling code here: https://www.vogons.org/viewtopic.php?p=918028#p918028 and my question is how best we use digital capture, i.e. what note, without any effects applied, etc to get any …

I think that there will be no "digital reference sound" since the final mix in original MT32 is done in analog. Also i think that because of analog mixing, some sound artifacts were hidden behind the op-amp. But i'll try different ways of digital mixing and interleaving to get as close as possible …

Hi! Last year after modding my MU-128, SC-88 Pro and Yamaha AN200 with SPDIF output, i challenge myself to mod MT-32. The complexity of the topic is that 6 channels feed in series to parallel DAC (clean stereo, 4 reverb channels), and then they demuxed to analog into 3 stereo pairs and then mixed to …

I have searched but did not find anything about the Zynthian hardware that looks (perhaps a bit overkill and expensive) like a very interesting hardware for MT32 and GeneralMIDI synth emulation. Have anyone seen that project before? http://zynthian.org/ Would it be a good hardware for this? http:// …

It's not MT, as it's not based on LA through GM map. I's definitely early version of SC/GS, alpha version :) Yes, obviously. :) I was just thinking of the appearance and the presence of 1/4" jacks. As for alpha version, as I said, it seems to have come out AFTER the SC-55, which casts doubt on that …

What kind of mod do you mean? There's a fix for the Vibrato issue being too fast for the CM-500 and CM-32LN that reprograms the control rom and replaces an oscillator. So it changes the sound to what's expected from the CM-32L. I am planning on modifying my CM-500 for the correct vibrato, but I'm …

Any interest in recording the sounds of a CM-32LN before I mod it? What kind of mod do you mean? There's a fix for the Vibrato issue being too fast for the CM-500 and CM-32LN that reprograms the control rom and replaces an oscillator. So it changes the sound to what's expected from the CM-32L. I …

It seems to be impossible at this time, since i'm in Russia and the postal services are unreliable due to great logistics problem (due to f..ing war started by mad creaker). You can order the pcb's at PCBway or JLCPCB, and AK4103 is found at Aliexpress. Gerbers for pcb production are on github. Then …

Yes, it's my mod i did in 2016, last month i have published it with all details at github. https://github.com/vetal-esher/18bit-DIT For Rolands , i have SC88 Pro and MT-32(old), and now i'm working on digital mod for MT-32, we all know that it is possible but without reverb since it is in chain …

May be little late, but i have modded SC88 Pro with digital output. That may be point of interest for the records.

Hi! That's my link @esher.ru It seems that Yamaha used early version of SWP tone generator chip (XQ036A0 aka SWP00), where digital stereo output was split to LD/RD (DACLR and DACR pins @uPD63200), so it will not work with AK4103 because it have only one Audio Serial Data Input Pin. You need to …
