Can we get an A/B switch to toggle between muting the internal synth engine and muting the MIDI port?

Hello,

I tried to convert various 4 op FM sysex to DX7 format without success. I used DXconvert 3.0.4 with python.

The sysex contain DX21/DX27/DX100/FB01 sounds. I know that conversion is not perfect, but I assume that lot of presets will be ok. And I like 4 op sound, different from DX7 character.

So, if anybody could convert those sysex to DX7 format, I would be very happy.

Thank you for any help

I'm not sure if this imports Yamaha 4-Op patches, but it is a great emulation of the TX81Z/DX11 engine that featured the extra waveforms in the operators...

May I ask why DXconvert wasn't working on these?

Interesting. It hasn't generated many usable sounds yet but it's fun to play.

Yeah, I tried this but came up with about 2-3 useable patches out of each batch of 32.

Just got a couple of good ones. It's quicker than I am.

For someone doing a machine-learning patch generator, tackling FM is a courageous decision. ML likes continuous spaces, something that fits analogue subtractive pretty well. FM is pockets of good swimming in a sea of "ow, those ratios hurt" noise.

It seems to make sensible decisions on things like envelopes but gets tripped up by the discontinuous space of usable FM ratios and a tendency to pick fixed ratios too often. It's a good effort though.

I'm importing into FM8 so it's nice and quick. Just saving the ones I like with sensible names.

It can be worth setting the ratios to sane values if you come across one that's got some interesting envelope movement in it. That expands the usable range of sounds a bit.

It's probably a bit quicker to do that in Dexed than in FM8 because of the way the coarse and fine settings are controlled.

Because I don't know how to use it correctly

Yes, it's a fine synth, but there is no way to import sysex, so the purpose to convert Yamaha 4-Op sysex to DX7 sysex format.

Here are some directions you can adapt as well as get yourself a free Korg DS8 emulation:

Yes, it's a fine synth, but there is no way to import sysex, so the purpose to convert Yamaha 4-Op sysex to DX7 sysex format.

But a 6-Op FM synth wouldn't sound the same as a 4-Op one, since the algorithms aren't the same. If you convert 4-Op algorithms to 6-Op ones, the sound may change anyway. So if you're looking for "authentic" 4-Op FM synthesis, wouldn't it make sense (and be easier) to just use a 4-Op synth?

I'm just curious about this, and not criticizing your approach.
