Seamless Sound Transitioning

[janrhansen]

It's the price you pay for using a VLSI instead of virtual software sound generation. It's much easier to implement in software. They would need to reprogram the whole base OS System of how the SWP70's is set up  to somehow give us real SST. Like other posted, you can prealocate different voices in each part to have the effect of SST betwen different keyboard parts. Think Yamaha is the last of the major Synth companies that still insists on using VLSI based tone generation, most other synth manufactorers are using software only based sound generation on either some kind of off the shelf computer parts or their own proprietary hardware. Many smaller synths focused on a particulary kind of sound generation, like all the smaller Korg Synths run on just a small Pi compute module, maybe with an added dsp chip for sound processing.

Not that there arent plusses with using them, but with their new software plugin of the Montage M I hope Yamaha finally kills this archaic way of designing their synths for the next generation. They have to use these VLSI's chips for several generations to pay back the cost of designing and producing them, and it's still a software programable chip, so why keep using it when todays cpu's is hundreds of times faster than what they were back when VLSI's was first introduced. Back then it was a necessity as the CPU's werent fast enough without adding expensive DSP chips.

There are 3 or 4 videos on YouTube from Keyboard Seminars on Seamless Sound switching. Unfortunately they're in Dutch (or German) and I can't catch much of what he's saying but something about DSP, Right1, Right2 and Right3..
He's speaking more than actually playing..If anyone speaks Dutch and would like to report back...

hi Luc,
Those videos are in German and you can turn on subtitles and then automatically translate them to your preferred language.

It actually *is* possible, but takes more work on our part (and no, it really shouldn't be up to us). But you can do SSS even using all 3 voices, but it's *very* complicated. You have to match the internal volume of each part, additionally, to avoid sample buffer flushes or sudden DSP switches (which can make quite a loud pop) you probably want to use a legacy or gm/xg as one or 2 of the 3 voices (fun fact, if you use all 3 voices as GM/XG, you don't even need to do any special programming in that case! They *all* used to be SSS until around the 2000's)

Long story short; just assign R1, R2, R3 as your different voices that you turn on and off, would be the simplest.

This is the way.
It is all to do with volume matching

Hello,

What I posted on our French forum as soon as this video came out:

"I'm posting a video that explains how to master SSS ( Seamless Sound Switching ) on a large part of Yamaha keyboards with R1, R2, R3 .

This video was posted today, and although it's only in German (too recent to have all the translations), the images and sound are demonstrative ... a must-see for yourself!

To avoid DSP shock when switching between 2 voices, especially when there's a Distortion, it's important that the next voice called is not on the same Midi channel, given that R1 or R2 or R3 each use a different channel. It's always the same assigned channel, whatever the OTS of Variations A, B, C, D or the choice of Voice on registration...

Clearly, for the transition to be seamless, the voices must switch from R1 to R2 or R3 ... whatever the variation or registration.

All you have to do now is test your disturbing transitions.

Another disturbing point I sometimes have on the bass of certain styles using Distortion: a note becomes too loud with an abnormal, unpleasant Distortion. It's always the same note, and I've spent a long time trying to find a way of eliminating this problem!  And I found ... only last week this resolution!

It's probably due to a DSP switch, from one style to another, given that the Bass is mostly on the same channel ...

To solve this problem, while playing, I opened the Mixer Styles / Effects page to access the Bass Distortion Effect ... I just changed the Distortion quickly in 2 clicks to return to the original programmed one, which eliminated this unsightly note ...

For me, the Mixer page is the most important screen used for display, and I have it on Assignable A.

If anyone speaks [German] and would like to report back...

If you would share the link, I might have a go at it.

But I do think that what they discuss will be the same as the tips in this thread.
