can someone please verify this?

Hello!

I am new to this forum but have been playing my V-Synth version 2 (the original model) for about 6 years now and I still think it is one (maybe even THE one) of the most amazing and inspiring synths ever created...I love this machine!

However, recently I discovered something which I cannot explain....so I hope someone is willing to try this on his or her V-Synth.

The point is: I initialized a patch (to make it simple) and activated STRUCTURE 1. You can turn off all the segments except the COSM 1 block and choose the COMPRESSOR for this block.

Now activate oscillator 1 and choose a stereo sample for this one (one you imported, or resampled, but it has to be a stereo waveform). Now play the keyboard...of course everything is fine now and it all sounds as expected. For the record, it doesn't matter if you turn VARIPHRASE on or off.

Now...turn off oscillator one and activate oscillator 2 and choose the same sample as above for this oscillator.

Play the keyboard again...there is no stereo anymore (at least it sounds this way)...it definitely sounds different.

The same thing happens if you change the STRUCTURE to 2.

Only when you choose STRUCTURE 3 the two oscillators sound identical.

So my conclusion was that with STRUCTURE 3 the oscillator is routed directly into the COSM block and then into the MOD block.

With STRUCTURE 2 oscillator 1 is routed directly into a COSM block and oscillator2 is first routed in the MOD block and then into the COSM block.
So I thought this might be the cause, however this doesn't explain what is going on with STRUCTURE 1 because BOTH oscillators are first fed into the MOD block and then into a COSM block...yet there is an obvious difference in sound...and there shouldn't be because with STUCTURE 1 the two oscillators are just summed together.

Also try changing the COMPRESSOR to SBF 1 ....again you will notice a big difference.

Can someone please verify this...that would be great?

Even better...maybe someone has a clue what is going on?

Many thanks and regards to all of you!

Good point, Pieter!

I have just tried all the possible routing configurations for OSC2. My conclusions:

• OSC2 loses its stereo character when going through COSM using structure 1 (the same thing happens whatever COSM type you chose except 'THRU', and the same happens when you turn COSM1 off and COSM2 on)
• OSC2 loses its stereo character when going through COSM using structure 2
• everything works as expected when OSC2 is going through COSM using structure 3

Looks like a bug...

Btw, I have a V-Synth XT with OS 2.02

Hi EXer!

Thank you for trying this! At least I know now it is is not specific a problem of my V-Synth.

After some further experimenting I found out the following: as soon as you activate oscillator 1 and choose a stereo sample for this oscillator...oscillator 2 also sounds stereo. You can easily test this by turning on oscillator 1, selecting a stereo sample and turning down the volume of this oscillator.

However, as soon as you select a mono sample for oscillator 1...oscillator 2 also turns to mono.

So the conclusion must be that oscillator 2 can only sound in stereo if oscillator 1 also is in stereo.

I think you are right that this is a bug.

I contacted Roland Benelux (I live in The Netherlands). After 2 e-mails I finally got an answer from their product-specialist but he was unable to duplicate this problem...but I suspect he was using a V-Synth GT because he was using some waveforms that are absolutely not present in my V-Synth.

So I send him a WAV-file of my own but I got no response.

I am very happy with the V-Synth but I can't say that about Roland's product support. I know the original V-Synth is an older machine of course but when you compare this to Kurzweil there is a huge difference in theit attitude...at Kurzweil you get a reply within 24 hours.

Anyway...many thanks and best regards!

Using a sample of my own (Stereo) I've tried to recreate what you mention on my V-Synth XT v 2.02, and my conclusions are:

Structure 1 and 2:
Turning OSC2 on it does not lose the STEREO character if the COSM2 is set to THRU

Could be a bug, but on structures 1 and 2 the COSM2 is ALWAYS behind COSM1, and in any situation it is the other way around...so I think that this problem has to do with the COSM2 being in Series after COSM1.
If we could do the oposite (COSM2 --> COSM1), maybe we would get the same issue, but in this case with OSC1.

Structure 3:
Turning OSC2 on never loses the STEREO character irrespective of the COSM2 setting. Makes sense as the COSM blocks are in parallel, so not interfering with each other.

Make Music and be Happy !!
