Zebra 3 fm ooperator suggestions

[gentleclockdivider]

Some sugestions for zebra 3 fm module
It would be great if the fm modules had a side chain input so it can accept 2 or more parallel operators , atm we need to use the mix module ,and things can get cluttered pretty fast .

Another suggestion and this one is a bit difficult to explain .
On the original dx operators , whenever an operator is set to self feedback , the gain/level output of that operator ( while being modulated by it's envelope ) is also affecting the feedback amount , because the op. vca ( when modulated by the operator's envelope ) is routing less gain into the feedback loop ( something yamaha missed on their latest dx reface series )
Example with a decaying envelope ( to zero sustain ) a feedbcak operator would go from saw ( self feedback ) to sine while also lowering in volume
It would be great if zebra 3 fm module had an optional dx setting where the gain output also controls the internal feedback amount

In zebra 2 , to do the same thing we need to modulate both the self feedback and the volume by the same envelope ( using a mmix module )
The advantage of the current feedback implementation is that it's independent from the operator's volume output , unless we want to re-create dx patches

I actually didn't know that - but then, I only have a TX81z, and all I needed it for was that one patch. Oi, I can check on the Arturia

One point about Z3 is that we're ramping up mixing options in the Grid. The current mix modules are vastly under-specced.

A side chain for a second FM source is a good idea though, I'll keep it in mind.

Same thing on the tx ( in fact all yamaha fm synths except reface ) , feedback is always dependent on operator output volume
That's the beauty of the original dx series .
When you just use one operator directly to the output and feedback enabled ( operator 6 , algo 32 ) with a decaying envelope , not only does it fade out slowly but also loses it's harmonics because the fedback loop is receiving less and les gain .

It's unebelievable how Yamaha have missed this on their latest reface dx
While they have implementd + and - feedback as a feature ( negative feedback is just the op.output squared and back to itself = square wave ) , the feedback is totally static , iow the operator env ,vca has NO effect onthe feedback amount .
On the reface dx , a decaying envelope on a feedback enabled operator will gradually lower in volume but not lose it's harmonics .
Therefore I used the term ''post envelope feedback " for the original dx series

Another suggestion would be the ability to un-sync the fm operator to gate on , just like we have in the other osc's
This has a huge impact when playing mono legato-style and adds a certain randomness

[Urs]

Yes, definitely.

Ohh and one more thing (if possible )
The possibility for operators to be non key tracked and 0Hz so they can be used as pure sine shapers , on the dx7 the lowest is 1hz but this is amazing whenplacin between 2 operators for added motion , modulation effect .
Sadly in zebra there is this artifact wh en oscillators and fmo's play really low ( around 2 hz ) there is a pitch foldback ( no aliasing ) , really high frequencies are heard
I think I have mentioned this many moons ago .
The option to oversample an operator when set to feedback is also most welcome , since it just gives that extra , I replicated the most famous solid bass patch and this was indeed the most difficult part



Keep up the good work , and stay safe

yeah being able to use a really low fixed freq carrier would be neat. I think using the sideband module produces the same sort of result, just that FM gives you the weird variation in amplitudes of sidebands.

another thing (I'm sure this has probably been requested a bunch of times) - tuning modes a la Bazille would be really nice. doing more straightforward FM stuff like setting up particular carrier:modulator ratios or fixed frequency oscillators is all there in Zebra, it just takes a bit of extra work and setting up presets.

I might be stating the obvious here, but perhaps others could benefit:
1) 'Filtered FM' mode is worth trying for milder waveshaping.
2) FMOs can be sent WAY below 2 Hz by negative modulation e.g. from a mixer module. If you need it even slower, even to 0Hz, put a 2-value Map or two in there

I forgot to mention that this bug only occurs when the fmo is set to stereo mode , and not just with the fmo but with all osc's set to either dual ,quad eleven .
How to reproduce
Insert fmo , set to lowest pitch , even lower when disabling keytracking
Set fmo to stereo mode , now play the lowest note on your keyboard

With some clever use of the osc effect (scrambler =self feedback ) , I managed to get a perfect triangle
so osc 1 ( + 1 octave ) as modulator , osc effect set to scramble ,and phase adjusted in partial setting into regular fm osc

Please can we have more than just sinewaves I know between wavetables is out of the question due to CPU overheads, but FM/PM between analog waveforms, like Bazille (but with Zebra filters ) would be awesome.

There are additional waveforms ( sine variations ) when you click on the fmo tab

Yes but no saw, square etc. Saw(C)-Sin(M) and Square(C)-Square(M) are very common combinations for complex timbres in psytrance sound design, for example.
