I would like to apply an LFO on pitchbend values and send them to a hardware sampler that can receive pitchbend informations. And I would love to use the mod wheel of my midi keyboard to control the amplitude of the LFO. Do you think that would be possible?
The second bit is the easier: you map the LFO depth to your mod wheel.
The first is tricky at first glance:
look at Transform when you set What=Control Change and Into=Pitch Bend,
then you see you get Set Pitch Bend LSB toandSet Pitch Bend MSB to.
So youâve got two bits of data that might both need varying. In concert with eachother.
Change just LSB & youâll only get micro changes. Change just MSB & youâll get bigger jumps in pitch.
That might be OK for what you want (partic if your synth allows you to set PB to a small semitone range[1])
As far as I can see, co-ordinating two LFOs would be a challenge. Not impossible.
Try Transforming an LFO CC into just one of them to start âhearingâ your way into the task!
If the sound youâre trying for is a bit more tolerant of two LFOs acting independently then youâre OK
(but youâre still talking of relative rates equivalent to 1/16 vs 8 bars!)
Both these LFOs internal?
Later: [1] I did couple of little tests with âcoarseâ Pitch Bend on a small PB range. I might be enough for what you want.
Hey thanks for your idea! Itâs working! Though I donât really understand how these MSB & LSB values work. Do you know a bit more about this ? I would love to being able to have a big amplitude with my LFO
Gives 128 x finer âresolutionâ than CC (though I bet few of your controls with a PB wheel/strip go close to achieving that resolution!)
Do you mean the effect of the maximum LFO depth being more than say ±6 semis?
Can you change PB range in your synth? (many will allow a maximum range of ±2 octaves, others (eg some Volcas) will respond to PB but not allow you to change the range.)
Yeah youâre right the maximum pitchbend range comes from my hardware sampler. I will have a look at it.
I have a last question about it regarding the mapping of the LFO âdepthâ value to my modulation wheel : I would like to limit the maximum depth value to 64. I tried the limiter pipe on CC1 but itâs not workingâŠ
yep, the the full range of your mod wheel will go through to the LFO depth.
(Currently) it doesnât matter what you do to CC1 after it enters Midihub, the LFO will respond to the value that enters the Input ie. {0-127}.
So Iâm afraid itâs a case for a loopback if you want to Rescale CC1 to {0-64} before it enters that Input.
So Question: will this be part of the same patch we did about a month ago?
(post it up?)
This use of loopback will be simple in comparison.
Ah ok I see!
Yes itâs actually for the same patch
I thought of the loopback idea, but do you think that would work using the existing loopback? I donât have any OUT leftâŠ!
should be able to use same loopback. probably using a separate pipeline. just need to take care with filters.
At worse, you might need to Transform your CC1 into say another CC/ channel/ whatever (& map that to LFO) âjust so you donât get the same thing passing through both ends of the line (ie. endlessly!)
Hey @klutio, as a postscript:
I discovered when testing for you the other day that one of my controllers - a KeyStep â didnât transmit a genuine Pitchbend (all the LSB values were 0, ie no greater resolution than a CC).
Testing others, I discovered that all of my âgenuineâ PitchBend âproducersâ are more than 20 years old!
So I guess your patch will do as well as most âmodernâ controllers
