Re: TX802 Factory Banks

Hi Jon,

I'd be happy to -- except that it's probably a little disappointing:? just two small banks, maybe? 20-25 sounds each.? A few of the sounds are detuned clones of other patches to use as a detuned layer set.? It would easily fit in a pair of original DX7's.? ?

________
Backgrounder:? I play in a one-man act called Bruce Andrews and the No Street Band ("No Street," because there's no band).? I do a lot of '80s and '90s, and the DX sound was a big part of the '80s.? My rig, though, has a lot of other sonic pieces:? Nord Stage 3, DSI Tetra, SampleTank 4, Minimonsta, Oddity 2, and Cakewalk by Bandlab to hold it all together, and provide prerecorded backup harmonies.

As such, I'm not trying to emulate subtractive synthesis; I have one real analog synth, and three virtual ones, at my fingers.? I'm also not trying to emulate piano, saxophone, or strings; the Stage has that pretty well covered.? The OPS7 only has to fill in the 'DX-y stuff':? glassy bells, synth pads, etc.? Sometimes extra horns and harpsichord, when the Stage is too busy doing other things.? Maybe a pulse line to mimic a chugging rhythm guitar.? I don't even use the 'DX Rhodes' sound; I never liked it that much, and thought it was overused back in the day.? And I never did much with alternative tunings and such on the TX.? But for say, Tears for Fears, or a song like "Drive" by the Cars, it takes center stage.

________
It might be more helpful to describe my 'recipe' for transferring sounds from the TX802 to OPS7:

  1. Start by exporting the sounds from the TX by SysEx.? Most of them will come through surprisingly intact.
  2. Set the OPS7 resolution to 15-bit; the stock 10/12-bit sounds too grainy to my ears.
  3. If a sound has a pitch envelope, the Pitch EG Amount is going to have to be cut to 1/4 to 1/3 of the value that was imported from the TX.
  4. Take a look at the frequencies of OP1-OP6; most of the time, they transfer properly, but I had one or two cases where the values were off.
  5. After that, use your ears.? There are subtle -- and occasionally, not so subtle -- differences in decay rates, particularly on release times.? I'm not sure how much of this can be chalked up to the OPS7's emulation of an *original* DX7, rather than the Gen 2 models.
  6. The OPS7 is a little brighter and 'edgier' than a TX802, so you may want to tweak the level of some operators to compensate.? (I like the brighter sound, so I did not do this.)

and finally:

  1. Throw out everything you know about the TX802's Performances and architecture.? The OPS7 is closer to a DX5 with better DACs.? In order to do complex splits and layers, one is likely to need to run multiple instances of OPS7 in a DAW.? The good news:? I run up to 4 instances in Cakewalk on an older i3 laptop, and it's pretty stable, even live.? And the 16-note polyphony limit is gone!? ?
Regards,

Hey?Bruce!

Any chance of sharing your OPS7 banks with the corrected?patches? I've got OPS7 and that sounds like a blast to check out!

For anyone who is interested, the TX802 banks loaded fine without any more fuss than mentioning "Multiple F0/F7 Found!"? I haven't extensively played around yet, but they sound pretty much the same.? I don't expect to spend too much time tweaking envelopes and levels.

With a lot of spreadsheet time, I was able to condense my 64-patch User Performance Bank into something that fits the Bank A/B architecture, and doesn't use more than two instances of OPS7.? The hardest part was moving Voices around to balance them between the banks, something that seldom comes up in the TX802:

  • The TX802 is 8-part multitimbral, with one user bank, and limited polyphony
  • Two OPS7s is 4-part multitimbral, with four user banks and comparatively inexhaustible polyphony
Epilogue:

I've finished my port from my TX802 to OPS7.? I did find a couple of wrinkles in the translation:

  1. In one -- and only one -- patch, OPS7 selected a frequency of 8.00 for one modulator, even though the original patch used 12.00.? I have no idea why!
  2. Pitch EG modulation was off in many patches.? It seems that the scaling for Pitch EG Level is off by 2x, or maybe even 4x.? I set the scaling to 0.5 and things came back 80-90%, then I tweaked a little.? Not having a DX7 for reference, I don't know why this is.
  3. OPS7 doesn't seem to support real-time CC7, so volume control on stage requires some ingenuity.
The end result sounds more like a DX7 than a TX802 to my ears, even when setting up 15-bit DAC output, but as I mentioned before, I kind of like the edginess.? To be fair, the OPS7 doesn't claim to be a TX802; it's closer to a DX1/DX5 in capabilities, with the option of better DACs.

I've also used up to four instances live in Cakewalk by BandLab, with good stability.? So converting TX Performances to OPS duals was easier than I feared.? All in all, I'm happy with the VSTi.
