InterpolatePresetsproblem.kym

I've found a problem with the InterpolatePresets sound, which is demonstrated in the attached file. Probably it is best understood by looking at my attachment, but here is the description:

The problem occurs if several identical values appear in adjacent presets, that are then automated with an InterpolatePresets sound.

Say !Value is a hot fader you want to automate with the use of InterpolatePresets. If you have 5 values of 0 saved for the first five presets for !Value, and then a value of 1 for the final preset, when the InterpolatePresets fader (!Preset) is used, the !Value parameter should stay at 0 for the first 5/6ths of !Preset, and move from 0 to 1 within the last 1/6th of the !Preset range. Instead, it moves from 0 to 1 evenly over the entire range of !Preset, as can be seen in the attachment.

There is a way of getting around this problem: you can assign a preset value very close to 0 for the 5th preset, but not 0, and in this way force the values to remain very close to 0 for the first 5/6ths of the range of !Preset. That way it has something close to 0 to interpolate to over the first 5/6ths of !Preset, and it does pretty much what I had intended. Unfortunately, it adds quite a bit more trouble to go to in setting up your presets, because you have to notice if your adjacent presets are repeating values.

I assume this wasn't the way it was intended to work?

thanks,
