I am using a groove~ object (which is sync'd to global tempo) to play samples stored in a buffer~ object, and replacing the sample in the buffer~ while groove~ is still playing. I am hoping to be able to trigger different loops from the same groove~ object but have the loop triggering quantized, similar to the way Ableton Live works.

However there is a slight delay before the groove~ switches to the new sample - everything stays in time but the samples are changing over slightly after the beat.

Does anyone know if this is normal behaviour and if there's any way to eliminate or reduce the delay?

Reading data from a file into RAM—which is what you're doing when you replace the sample in a buffer~—takes a small-but-imprecisely-knowable amount of time. It's better to do all your sample-loading beforehand if you need instantaneous access to the data. Use several buffer~ objects, or a polybuffer~, and then use the 'set' message to groove~ to change the memory location to which your groove~ refers.

My first step would be to make a buffer for each sample, and to send the buffername to groove, instead of reloading the sample in one singular buffer, or use a gate to send the next beat to the next groove

polybuffer~ doesn't quite fit my needs so looks like I'm going to need 128 separate buffer~ objects, time to get patching!

Still having some problems with this - as advised I have multiple buffer~ objects and I'm using 'set' messages to select which buffer is played by the groove~ object, however I am still getting a slight delay before the new sample plays. Any ideas?

My groove~ object is set to follow global tempo, and the set messages are sync'd to a metro object which is also following global tempo using @quantize and @active 1 attributes.
