Recording Into Buffer (Without Specifying Buffer Size)
Jan 15 2014 | 7:05 am
Hey everybody.
The topic title says it all really! I’m writing a patch that allows users to record into a buffer, starting with a toggle on, and ending with a toggle off. This all works fine when specifying the buffer size (buffer myrec~ 10000) but this only allows a limited duration to be recorded.
Initiating the buffer with no duration means that when I record, there is no audio that actually gets recorded into the buffer.
Can anybody help?

Hmm
seems your pasted patch is empty too. Can you verify that you can open the patch above? If it doesn’t, try re-copying.
A common strategy is to initialise your buffer with a maximum size at the start of each recording, and then crop it as you need.
This demonstrates the concept, but was a rush job so caveat emptor and all that!

Perfect work around, the crop message is exactly what I needed. Thankyou both!
