Well since two of the other synths in the Dev's challenge have threads in the Instruments forum it's only fair that Reducktion has its own. :tu:

It's getting my vote based on sound and features. The other two entries are behind only by a fraction of a point as they are all very nice synths. Perhaps the best Dev Challenge class in memory for synths at least.

Here's some patches:
Reducktion Teksonik 01.zip
And some Theme Color Edits:
Minimal Blue 1.zip
Minimal Orange.zip
EDIT: Can someone test the patches with Reducktion 1.0.0.1 and see if the Arp and Seq patches are playing too fast or too slow or? I tried loading them up here couple of minutes ago and the Seqs were running crazy fast. Not sure what's going on. I'll have to work on it some more.

Thank you for your cool patches.

Trying your three SEQs pathces, there seems to be no problem here. They play correctlly at 1/16.

Thank you. :hug:

I don't know what happened here. The Seqs and Arps started playing crazy fast like 1/128 then everything is fine now. Ghosts in the machine I guess. :shrug:

I added a few more patches and tweaked the olds ones a bit:

Gave it a whirl. It's decent, with triple pannable oscillators, 3 envelopes and 3 LFOs. 12 mod slots. Dual filters. FM is basic but it's there. I like the unison implementation, and the stereo noise is a nice touch. Shame you can't unison the FM though. Weak points for me are the effects, the delay and chorus are ok but the reverb and drive didn't impress me much. A quirk with the random modulation: if you randomise panning at 100% it only pans between the centre and right, you have to set the oscillator pan 100% left for the modulation to work properly.

Overall pretty cool for a free synth.

I will try it next week. Anyone who already used it: how do the oscillators sound? What I'm missing in most virtual analog synths is the "drift" feature that U-He Tyrell has. I think TAL Noisemaker has it too. It adds very slight variations / drift to the oscillators pitch, too approximate the sound of analog oscillators.

No drift feature, but you can add subtle random pitch modulation to approximate the effect.

I can't reproduce this; modulating Osc Pan with a random LFO causes panning to the left and the right. Was the LFO Offset set to 0 when you tried this? If the offset was set to 100 it would show the behaviour you describe but that is as intended.

Sorry, I should have clarified: I am using the random option in the mod matrix, not the LFO. It seems to work fine if I set an LFO to random and use that. Using the mod matrix option will weight the panning to the right if set at 100%, and weight it to the left if set at -100%. Setting it at zero of course produces no effect, so it's not possible to use that option to produce a balanced effect without setting the oscillator pan full left or right.

Yes, that makes more sense. I suppose you could call this a quirk; its a consequence of having a modulation system that combines both unipolar (0 to +100) and bipolar (-50 to +50) modulation sources and targets.

To modulate Osc Pan around the centre setting you need to apply a modulation range of -50 to +50 which is what you normally get from the LFOs. A 100% random modulation generates a number between 0 and +100 so it will modulate the pan from centre to right as you have seen. In fact it will over-modulate as maximum pan right is at +50, anything over this has no effect.

To get random left/right panning you can set the pan to the left as you have done; here the pan starts at -50 and is modulated into the correct range by the random modulator (0 to 100 effectively becomes -50 to +50).

Alternatively, you can use the mod matrix to apply an additional 'constant' modulation of -50 to the Osc Pan to bias the random modulator to +/-50 around the centre point.

This technique is useful with all modulators where the modulation source is 0 to +100 but the target needs to change around its current setting.

Drift or no drift....to my ears Reduction sounds better. Especially the unison. I like Noisemaker but it isn't as harmonically rich sounding as Reduction. I have tried for years to like Tyrell. I go back to it from time to time as my ear and experience develop. I just don't like the sound or the envelopes. But to be fair. Reduction is new the other two are nearly a decade old.

EVERY soft synth should have a drift/slop knob. (and Pan/Spread too)

On both Reducktion and Deducktion, when holding a note with the sustain pedal, that note doesn't re-trigger.

Yes, both these synths normally ignore any further note-on messages once a note has started playing. This was designed for simple playback where you can't play a note a second time until you've released it but clearly using sustain provides a way to do this.

Thanks for pointing this out, I plan to review the whole mono/legato/retrigger behaviour in Reducktion so this is something else to think about.

Also dependent on the controller, on my LinnStrument I do that all the time. Any isomorphic layout has the same notes multiple times at different places. Think Bandoneon and you know what I mean…
