Trying to use a midi controller knob or slider to scan through the buffer in the mubu granular and the slider scans at intervals of 23.something and scanning w/ the mouse scans at intervals of 4.something, so not sure what I'm doing wrong. Also, when scanning using slider the red playhead disappears?

i guess bc i'm trying to work w/ a range of 3000ms and the midi is splitting the 3000 into 127 equal parts therefore the 23 or so ms intervals

but how do i get it to move at 4 ms or so intervals at a 3000 ms range using midi

i can get a live dial to have this range and play w/ the inspector exponent and division and stuff but the moment i attach midi values it goes out the window (which I guess is obvious to me now but sucks)

midi ctl is not enough range for this king of stuff.

look in here, at least few things are better, like

do you have some rotary encoders ?

reducing midi to buffer length


this is getting so close! kind of the same issue though where I can't quite get the same values as i would using the trackpad to scan? One interval on the rotary knob (0 to 1 out of 127) jumps 4871.68294 ms through the buffer, while one interval on the trackpad jumps 1041.759785 ms. Is there any way to get it as smooth as the trackpad?

What is that interval on trackpad ?
you have to post the patch



So I just wondering how i get the rotary interval down to the trackpad interval

in my patch:
trackpad interval is 4 ms or so
rotary interval is 23 ms

trackpad interval is 1041.759785 ms
rotary interval is 4871.68294

while keeping the full range of any buffer i load

only inserted buffer length - duration to limit midi to scale range.

I removed plenty of things just to have easier look at it.

You can simply insert that parts from patch I posted into yours and that should do.

I did not play at all with that patch,

Maybe I removed too much stuff.

curious tho--the lower we get the rotary scan interval the lower the trackpad interval goes--it's somehow always smoother? Is this something that just can't be worked around?

doesn't seem to be an issue w/ small buffers like in example patch w/ short samples but when i upload long buffers it's about a 5:1 ratio between rotary and trackpad

is this just an issue of midi rate vs. control rate?

10000 ms buffer / 128 = 78.125 ms per step

So also when using OSC you need a lot of steps to be smooth.

Or you try some sort of inc/dec rotary encoder.

10000 ms buffer  / 128 = 78.125 ms per step
120000 ms  (2 min audio) = 937.5 ms
and so on
