Had an idea for a Helix pitch block yesterday, while watching a Radiohead gig. There's no Ideascale anymore, so I'll post it here for
@Digital Igloo in case he finds it interesting.
It would be an auto-octave transition. Similar to the feedbacker but without sustain (no need to press a footswitch to enable it; it just rings while your notes are ringing).
It would have these params:
-Octaves: 1-2 (it would need the poly pitch algorithm, and I'm not sure if "semitones" would be better than just octaves)
-Sustain time (the amount of time the effect waits to be applied)
-Pitch time (the amount of time of the transition from your note to the pitched one)
It would work like this:
-You play any note or notes and let them ring a certain amount of time ("sustain time")
-After that "sustain time", a crossfade (not a glissando) starts (set by "pitch time") to the same notes played one or two octaves higher while the notes are still ringing (no need to sustain them)
-Whenever you play any other note/s, or you strike the same note/s again (assuming both events are easy to detect), you get back to your normal pitch and the effect is fired again.
The idea is to emulate the behaviour of an Ebow in harmonic mode, but without the sustain (that is, like the current feedbacker but without having to press a footswitch because no sustain would be applied). You rely on your guitar sustain.
I sold my Ebow long ago and rely on my Sustainiac pickup only, and the harmonic mode goes either to two octaves higher or some other pitch in other strings/frets. I miss that "transition to one octave higher", and with this effect and my Sustainiac in normal mode, I could have that Ebow thing again.
