Everyone should check out this set of sounds - there’s some really wonderful patches in there! Thanks for posting!!

Well, I’m not sure if this is really correct, as I see at https://electricdruid.net/roland-cross-mod-metal-sync/ the author states, > > Jupiter 8 “Cross Mod” is FM from VCO2 modulating VCO-1. This is described in the manual as “ring modulation style effects” which is true in as far as they can both ...

Well, it’s interesting that he states it is logarithmic FM instead of Exponential FM. That is a key to the results you are hearing.

Could you make an example of the 2 saw waves that you did, with the Cross Mod at full amount, then play across the keyboard, say, C2 E2 G2 C3 E3 G3, etc.?

A quick lookup of the Jupiter 6 states that the splits limit one side to 4 voices and the other side to 2 voices. That means one of the sides isn’t playing a ‘chord’, but in any case, it would be good to get a single dry sound example to analyze. Perhaps you can record without a split a single sound...

Well, I’d need more information. What are the Splits made of? What waveshapes? To start it, you play 2 chords...are they one chord for each side of the split? Are they the same chords for each? Can you just isolate one note without any effects so I can hear what it sounds like? I am completely unfam...

I also found this online:

"In the early VCO-based instruments, Roland used “Cross Mod” to mean frequency modulation (FM) of one oscillator by the other. The term is used this way in the Jupiter 8, Jupiter 6, and the MKS-80 module. These are the only synths that have this option."

It depends on what and how the Jupiter 6 is processing what they call Cross Mod. I know in a number of earlier synths, this was just audio rate modulation of the frequency, but it could also be modulating the VCA, or even the Pulse Width. Since the Solaris has several ways to modulate the amplitude ...

Here's my instructions on how to open. 1) First - there are 4 little black screws across the back that are holding down the hinge points of the lid. Take these out first. 2) There are 12 screws holding down the keybed on the bottom - these have to come out. 3) There are 6 screws (3 on each side) on ...

So, the situation is that all of the code that runs the voices (the whole synthesizer prior to the Main FX) is summed as a stereo signal at the input to the FX chip. (It appears under the label of ‘Synth’ as you find it in the Output page.) It’s not possible to bring out an individual mixer to then ...

Look for our big release of v2.0 OS, coming soon!

UPDATE - I have a new source of the ‘inverted background’ LCD to go along with the black OLED text displays, so we can offer the OLED upgrade package now without worry. I do need to know how many are definitely interested so I can place the order for these displays. The upgrade kit comprises of the ...

Hello Eric, and welcome! Please don’t hesitate to post any questions you might have, as I or any of the other active owners here I'm sure will be happy to answer them.

The question I would have is, what is the Synthex’s Ring Mod section using for carrier and modulator, and what amounts? Also, what does it mean to say Osc2’s waveform is 'Osc1 PCM + Ring Mod'? What are the levels, and balances? You are showing an estimate for the Solaris of 52% modulation of the PW,...

I will ask Jim to respond....

Thank you for the video. I fallow also the Solaris Sysex documentation and the table "Parameter Changed" page 7 I wanted to control the Env6 Attack, so I founded address low mid and high are 13 50 03, 00 12 34 for Manufacturer ID, 00 for Device ID, 10 for Solaris ID, 13 for Function: Parameter Chang...
