Sorry if this is fairly rudimentary but I'm a bit stuck. I am using record~ to grab a few seconds of live input and stick it in a buffer~ for loop playback. It seems that record~ doesn't work unless I give the corresponding buffer~ a size argument. For example: [buffer~ foo 2000]. My goal is to playback the buffer~ as a loop using groove~, but I want the loop start and end points to correspond with when record~ was manually started and stopped. As it stands groove~ loops the full 2000ms of the buffer~ determined by the argument I supplied as opposed to simply looping the recorded material.

Am I overlooking something basic about these objects, or is there a trick I need to employ to do what I want? (At the moment I am not supplying any arguments or commands to groove~ other than playback speed and startloop.) Thanks!

silly-problem-with-record-buffer-and-groove

give your buffer~ a certain size, lets say 2000ms and just start a timer when you start recording and use its result for the end looppoint of your groove~ when you stop the recording ...

there are many other ways , but i am in a rush right now...

Great idea, thanks! I thought maybe I had missed a functionality of one of the three objects involved, but it looks like I haven't.

There is a crop message to waveform~ which resizes without erasing, but 

as its a UI object it might be expensive on the CPU.

The opter approach is to copy the part you want to keep to another 

(I am real-time sampling all the time already... ;-)

This is a simplified example of the solution I'm using. Seems to be similar to what you're doing seejayjames. What wasn't working for you?

Oh, nevermind. I see, you're concerned that the buffer~ is wasting space it's not using. Gotcha.

Thanks Stefan, will look into it. Really would like to create a Max version of a "loop pedal"... because of course Max has a lot more capabilities than a lil' piece of hardware. In fact, using a simple MIDI footswitch or series of them, in conjuntion with buffers~, could make for a really cool live looping machine.

Any tidbits regarding your implementation of the real-time sampling would be great!
