I've created a patch that uses an OSC with TUNE set at -48.00 (maximum). With KEYSCALE set at a default the patch sounds 'right' to me when played very low, between C0 and C1. I'd like to set KEYSCALE to 0 and have the OSC trigger the same pitch that it does when KEYSCALE is 100 and C1 is played, unfortunately it doesn't (I think it plays E2?) and there seems to me no way to pull the pitch down any further. I've had the same problem using the COMB module too.
I hope my convoluted explanation makes some sense. Anyone know what I'm on about?
Low tuning of OSCs when Keyscale set to 0

It makes some sense and coincidentally I gave an explanation in the other thread. The center key is 64, which I think is E3 (or maybe E2, dunno out of my head). My solution for this would be a freely choosable center key. But I havn't sussed that out yet...

Oh well, it's no big deal - I just thought that there may be some work around that I'd missed. Anyway it's only come about because I was using the OSC well outside of it's normal operating range - kind of like an 'audible' LFO (it probably says something for the flexibility of Zebra that you can try stuff like this and still get usable results).

1. choose "gate" as the modulator for the oscillator pitch.
2. Then set the value to -12 for one octave down, -24 for two octaves down, and so forth until you find the pitch that you want...

Ah... I'd rather use an empty ModMixer in summing mode with the Const parameter cranked up, because Gate will fade to zero after releasing a key. Const won't

No, I've already tried modulation and that doesn't have any effect in this case. Thanks for the suggestion though.bagginz wrote:1. choose "gate" as the modulator for the oscillator pitch.

Try it yourself. Set TUNE on an OSC to -48 (minimum) and play C0 you should hear a periodic clicking sound at about 2Hz - set KEYSCALE to 0 and now play any note (they're all at the same pitch) and you will hear a much faster periodic click - equivalent to E2 when KEYSCALE is 100 and TUNE -48. Modulation will not pull the pitch down any further.
As I said it is using the OSC well outside of it's normal range, but with some OSC FX settings you can get interesting repeating effects this way.

well it works on my copy Zebra2
Note I said modulator and not modulation.
By "modulator" I mean the circle to the immediate right of the tune knob on the Oscillator module.
Right click it and select "gate" then move it to the negative amount you require.
Gate (everytime you hold down a key) will then modulate the pitch further downwards.
See Urs' suggestion above for a more sophisticated approach.

Yes, you're absolutely right!bagginz wrote:

Thanks for that
(funny how routing a modulator doesn't achieve the same effect? no need to answer Urs, I'm sure that there's a sound reason for it)
