For synth parts (at least) we need same kind tool what dynamics hairpin tool but controller values. and of course way we can write start of track for example LPF and this lane can have things like 1.5khz>500hz<2khz.
and customizaition how these things in middle look. allready tried way use wedges and text (idea what i get Facebook group) but things positioning needs lot of time even more thinking how i postion instruction what this exact parameter is for example is LPF needs be before notes. even nice postion y axis beetween text and wedge is hard archive even more when i have multiple parameters sametime. my idea is exactly similar hairpin tool but controller values and hairpins are replaced suitable stuff wedges look good.
