iOS sequencer where you shape each MIDI CC for each step

Is there an iOS sequencer where you can shape each CC for each note, including volume? I'm thinking something where you select the step, and then below you have a window with a drop down or selection for each CC where you can draw a waveform with the Apple Pencil or select from sine, triangle, etc. Including screenshots from Korg Multi/Poly Native & Cable Guys MIDI Shaper as examples of what that window might look like.

    No drawing, but take a look at Stacks by John Howes. You have a (very unconventional but interesting in its way) note sequencer and then a CC sequencer which can basically track the note sequencer or be set to do its own thing. Also a killer synth, tons of modulation options, even granular features too.

    Will check it out, thanks!

    A little bit off topic but ...

    Volume isn't a CC. You'd need to connect a CC to a volume control on whatever you're controlling.

    Velocity is part of the note message, and it may or may not affect the initial volume depending on the synth patch. It's a one-time event that basically says "here's how hard the note was hit". There's no shape to it as in how the volume swells or decays.

    I'm not sure I quite follow the question. Is it correct to say that you're looking for a sequencer that when a note is triggered can also trigger a set of CC's each with a custom envelope?

    So, say, CC 20 could have a slow swell from 0 to 127, then drop back to zero. CC 21 could jump all over the place, CC 22 could follow a different curve, etc ...

    Or drambo?

    Drambo can do that. It's not hard to set up.

    ...or like this, hello again Drambo:

    Correct, much like MIDI shaper, except as you say, it happens in a sequencer at the point the step is triggered (which MIDI Shaper doesn't do). Just thinking, for example, if you're scoring the next Star Wars theme, you want big swells and decrescendos and some tonal articulation on long notes without having to trigger a new note.

    What prompted me is watching some of these sequencer tutorials and seeing that people are playing everything like a piano or organ regardless of the patch, and it sounds like training video music doodoo. There's no thought of voicings being spread out, swells, or articulation. And in an orchestra, you wouldn't have all the instruments in exact synch. They would be slightly out of sync in volume and timbre, variations in attack and articulation, and there would be some portamento. So I think the answer if you want to get a good sounding musical phrase (even if it's electronic-sounding music) is to program each note as monophonic individually, with specific volume and articulation that changes over time.

    I have Drambo installed and will check it out, thank you!

    If you're after this very organic sound, you'd really be best to just use mpe synths with an mpe controller, whether virtual or hardware, playing everything by hand, while recording it in a DAW or piano roll that supports MPE.

    That's definitely an option, and Osmose is on my wish list for sure. However, that conflates the process of composing with the action of performing.

    how do you assign the waveform to anknob lets data cutoff filter in an AU synth?

    Unfortunately I still haven't figured out how to make it cook and clean...
