@Thor_Madsen : could you elaborate how you are using your \simpler SynthDef?
I have recently opened this topic about a similar subject. I wasn’t able to find a SynthDef that makes it easy to mix/match different looping samples with patterns. I am thinking about something rather straightforward that plays for instance a sampled drum loop with a sampled bass loop together (matching tempo if necessary). The goal would be to live-code long samples/slices in a smooth and pleasant way.
@sslew: I am very happy using SAMP made by @scztt. I am loading a crazy amount of samples without any issues (3GB+). My library is automatically loaded when the server boots. It’s super convenient. For simple sample playback, there are a ton of resources available. Maybe start by taking a look at this resource. It comes bundled with a few sampler SynthDefs that you can start to modify to your liking
