bg Posted September 16, 2006 Share Posted September 16, 2006 The Arturia CS-80V has what I consider a flaw in that when doing a trill (as opposed to a bend) with a ribbon controller, there is pitch smoothing between notes. I don't know if that's the right term, but it's like glide between the trill notes. I tried ribbon trills on other synths and found that most of them do pitch smoothing as well. As a test, I made a sequence consisting of one sustained note with manually inserted single pitch bend events alternating from maximum to minimum. I played the sequence on various synths and recorded the results. Warning: These audio examples are exceedingly boring to listen to. Obvious PitchBend smoothing: Arturia CS-80V NI FM7 Arturia MinimoogV K2000 - flute K2000 - saw Oasys-PCI subtractive synth algo Little or no PitchBend smoothing: DX7-II Oasys-PCI reed piano algo P-100 - Yamaha digital piano organ preset Proteus 2000 All the synths I tested which don't exhibit pitchbend smoothing also have no problem doing perfectly smooth traditional pitchwheel bends, so I don't understand the reason for implementing it. Anyone know why some hardware (and all softsynths I tested) impose PitchBend smoothing? Link to comment Share on other sites More sharing options...
mate stubb Posted September 16, 2006 Share Posted September 16, 2006 Because the developers were wrong?

Prague Posted September 16, 2006 Share Posted September 16, 2006 It sounds like Portamento. Explain a "ribbon trill" so I/we don't make a wrong guess about your findings. Link to comment Share on other sites More sharing options...
Tusker Posted September 16, 2006 Share Posted September 16, 2006 That's very curious. It does sound like some slow pitch interpolation (i.e. portamento). Is portamento switched off on all these synths? Typically portamento shouldn't affect pitch bend events. I'm just asking. I would expect more portamento like behavior in single triggering in romplers, simply because the sample is being re-pitched, and there maybe some processing lag. I saw no correlation between synthesis type and portamento in your list however. Sorry not to be of help. I am curious about the answer.

bg Posted September 16, 2006 Author Share Posted September 16, 2006 "ribbon trill" Instead of sliding up and down on the ribbon with one finger, plant one finger on the ribbon as an anchor and then hammer another spot on the ribbon with a different finger. For the audio examples, I manually inserted PB events in a sequence instead of actually playing the ribbon so that sloppy hammering wasn't a factor. The Pitchbend events went like this: -8000, +8000, -8000, +8000,... etc. (I'm in DP.) Link to comment Share on other sites More sharing options...
