Syntakt users: How stable/unstable are your Dual VCOs?

Necroing this thread because I have inconsistent tracking with my Rytm and Syntakt. This is challenging for me as I try to convert patches from one to the other manually, and just copying the settings 1:1 only works for some of the patches. I suppose there aint no fixing it, other than by using a tuner and offsetting the tunings manually to match, patch by patch.

Contrary to many ppl here, I dont actually mind the wild tunings, in fact I think they sound awesome on my Rytm, and wish my Syntakt sounded the same. Syntakt seems to have better pitch tracking, but smaller tuning range (TUN on Rytm goes to -32 / +32) so some of those wilder sounds from my Rytm are forever out of reach for the ST…

I’m guessing Elektron hasnt been able to improve the internal calibration algorithms since these reports? I wonder if they are still working on the matter… To be clear, I dont want a perfectly pitch tracking response across octaves, I just want to get those awesome Double Voltage sounds to sound as identical as possible on the Syntakt as well… Many of those sounds lose all their “magic” in the Syntakt somehow

Are you running the latest firmware on the Rytm? Until some version … 1.7 maybe, it had less stable tuning (and range?). After that, it got more stable. On the other hand, the Syntakt arrived with more stable tuning (as from release it was more of a “synth” than the Rytm’s “drum machine” basic role).

If you’re still on older Rytm firmware, you might find your wild Rytm patches get less wild (or more out of tune) if/when you upgrade.

If you’re rocking the latest versions everywhere, then I suspect you’re working with issues more subtle than I have experience of so I’ll stop here.

Latest Rytm OS I think - 1.70 right?

Thats an interesting point, I have no idea how these Double Voltage patches are “supposed to sound”, so no idea if they actually sound wrong now hehehe! But I love em. They sound the business and crowd reacted to them vary favourably on our last 2 gigs

Sounds right.

OK, so you def are now in the zone where you’re discovering variations between two seemingly similar machines. I’ve also got both, but havn’t tried to recreate sounds from one to the other.

There arent a lot of differences, aside from the Rytm having +/- 32 semitone range for the TUN parameter. But the tuning stability of the oscs is also different, Syntakt is much steadier, for better or worse

I had to set mine to -12.09 right after power-on.

I’ll let it warm up for a while and see what happens…

Update: 5 minutes in and I’m at 11.97 (on track 9).


8 minutes in:
Track 9: -11.91
Track 10: -11.97
Track 11: -11.93


16 minutes in:
Track 9: -11.89
Track 10: -11.91
Track 11: -11.875 (between 11.87 and 11.88)

It’s not linear, either. This was on note C5 but it’s different if I octave up/down.


30 minutes in, the Syntakt is starting to get warm to the touch:
Track 9: -11.91 (going back up!)
Track 10: -11.91
Track 11: -11.96 (a long way back up)

Note: I don’t think any of them are 100% perfectly tuned - the control isn’t fine enough.


At least we know it really is analog. :slightly_smiling_face:

Dual vco on syntakt and overall analog machines are much more stable that those found on the rytm.i had very instable vco on the analog 4 also.to the point it sounded very bad, run calibration was good but i had to do every day.Dual vco is like a complex Oscillator wescoast style. It originated on the rytm and Thus i never approched This machine to be perfect pitch tracking synth but more as an analog fm percussion style vco. If i want to make melodies i go to the raw machine wich is Kind like a simple Roland sh-101 machine and it perfect!

It’s not a defect, it’s just part of owning a real analog synth.

You can turn on oscillator reset to make it more predictable when you’re playing short notes (little squares on the start of the note).

Some old synths had a “sync” switch to deal with this “problem”.

I didn’t even know I could do that. :rofl:

I’ll try it to see what happens… but perfectly synced oscillators are boring. :-1:

Update: I did a calibration and it doesn’t seem to have changed anything - values are the same as before.

Not perfect without PWM. :angry:

(Syntakt needs a proper 2-oscillator machine with PWM+saw…)

ah nick we spotted you :rofl:

indeed compared the dual vco with both oscillator’s at 0 with the raw machine and there’s definitely less beatinfg / phasing on the raw machine

i may be dumb but i don’t see any pwm on the dual vco also

you can easily achieve something like this with the bits machine although

There’s no dual-oscillator-with-PWM machine. It needs one, badly, IMHO.

Still not PWM+Saw. :slightly_smiling_face:

PWM+Saw is one of the true great synth sounds, eg. The lead synth sound on Gary Numan’s “Cars” (aka. “Vox Humana”), Kraftwerk’s Computer World (also a Polymoog), etc.

Again, I am not looking for patches with “perfect tuning across the whole range”. I am merely trying to recreate those awesome lead sounds from the Rytm Double Voltage pack, which in hindsight seem to have been tailor made for the specific DVCO voicings a Rytm uses. Even slight deviations from the tunings will ruin all those detuned hoovers and FM timbres to a point where they no longer sound appealing.

I fear the only way to replicate em at all on the Syntakt, to the degree it can anyways, is to play the same note on both machines and using a tuner, setting all the tuning values according to the tuner readings, oscillator by oscillator… which is a bit more work than I’d like to be honest…

i NEVER use pwm , never so i’m good. if your sound/music rely heavily on pwm why buying a synth that does’nt have real pwm, i guess that’s on your side ? the chip machine also have PWM.i guess if elektron gives us track layering as in digitone2 we could create any combination with the current great machines at our disposal. you should fill a request toward elektron.

Why not just use two tracks to achieve what you want? Track layering opens up a whole lot of additional sound design possibilities like multiple filters, individual modulation etc.

Not a Polymoog by any means, but the Chip machine does quite nice pads:

I see :slight_smile:

also keep in mind the analog parts ,even if it’s a very forward thinking machine in terms of analog , maybe the analog componants are not there to do a proper dual oscillator with PWM. so maybe just doable in a digital machine like digitone yes.
