    Very short update: your patch is working fine, David, and i'm having good fun with it, There is still a small leap as I was saying, no matter the change i make, but it is just same when controlling the synth from its own panel, it is just part of the hardware limitation. Thanks for your help again David.

    Thanks again David, unfortunately i won't have free time before the end of the week or next week to look into that now!

    The midi and/or synthesiser processor do already saturate when i'm tweaking the 4 knobs at the same time alright and the synth screen is freezing for a while!

    ... Sometimes nice sonic accidents happens during these system overload moments though ! :)

    @whale-av thanks so much for your suggestion, David! Much appreciated! That is smoother that what i got for sure!

    Now there is still a small leap when reaching a new integer value on the oscillator (especially with the carrier), even with very long [line] values (like 6000ms), but i think it is due to the inherent limitation of the (low-budget) Reface DX tone generator and not really to the design of the patch.

    I need to find how to control the operator the same way when it's in "fixed frequency" mode (as opposed to "ratio" mode) but i dont have the time to work on it now. If i'm stuck i'll post something here.

    I attached my abstraction down here if anyone's interested. You only need to add the number of your CC in the creation argument and with four of them in a patch, one can control in realtime the four operators of the Reface DX with physical knobs :) I've also added an inlet to change the ramp value in ms to experiment with different transition times.

    Thanks again David!

    Hi guys,

    I'm trying to assign a knob from my hardware controller to control the frequency of the operators on a tiny Yamaha Reface DX.

    Only "problem" is that on the actual keyboard Data List parameters there is 2 different CC Number for each operator frequency level: a "coarse" and a "fine".

    For example for the OSC1 of the Reface DX, the CC 89 (with value between 0-31) controls the Coarse frequency value (integer only), and the fine frequency is control by another CC (90) with value between 0 and 99 for decimal.

    (gosh, i hope i'm clear enough!!).

    I would like one single knob to smoothly operate the change of frequency because the audio rendering is quite bulky when only using integer value only and the charm of FM synthesis realtime morphing is then lost...

    I've tried a a patch that isolates the decimal from the integer from the midi control value and send the two values to the target CC number (89 and 90) via a [ctlout] object but the result isn't perfect really. I've put some short delay for the decimal values to be send before the integer value...

    Nothing very complicated for most of you i think, but i am an eternal newbie on PureData, and i could do with some help!

    Thanks for any advice guys!

    Regards,

    Anthony
