ISimpleMediaDecoder question

[IXix]

I'm trying to handle a file type which encapsulates four separate stereo loops which may have different lengths. I don't think I can do it with ISimpleMediaDecoder because in a call to GetLength() I'd have to report different values for different channels and I can't see any way to do so.

Any idea how I could tackle this?

Subclassing PCM_source is the most flexible way to do things and pretty much involves just a bit more typing of code than ISimpleMediaDecoder.

However, I am not completely sure what you are asking about...? Can you explain a bit more in detail what you are trying to do? (Reaper doesn't have the concept of different media lengths for different channels of a single media file, to begin with...And does a "length" even make sense for a looped media source?)

The Kaossilator Pro has four loop slots which can be set to different lengths. You can save them individually and I've implemented importing those to REAPER but you can also save the whole device state to a single file which is much quicker and more convenient. I'm hoping to be able to get that file into REAPER and treat it as multichannel audio which could either be exploded onto separate tracks or just looped as a single item.

As a single item I could just report the length of the longest loop as the length of the media (or maybe a point where the loop ends converge) but if it were exploded that wouldn't cut it, the item loop point would be wrong for any shorter loops.

It might just be too weird to do but in REAPER there's almost always a way. I'm not familiar enough with what can and can't be done with the API to know whether what I'm attempting is possible or not.

Can you create an item with multiple takes with the API? Since takes can be different lengths that might make more sense although the takes would have to point to different sections of the same file. Is that possible?

It's possible to create items with multiple takes, but it might get quite tricky if you need to somehow do that from your media decoder/PCM_source code...

Yeah, I think you're right. Hmmm....
