I am fairly new to MAX and for my setup I want to create a simple looper in M4L but I need some advise to progress. This is my first useful project and below I have listed my wanted functionality and the challenges I have for each. Any advise to get me going further will be appreciated.

1) I need to record a variable length sound file. I was planning to use buffer~ -> record~ -> and then groove~ and load the wav file into a waveform~ object and play with the sound from here. However as far as I understand this model forces me to decide the size of the buffer beforehand and this is not ideal because sometimes I want to record something that is 2 seconds and next time maybe 2 minutes. Please advise any alternatives/workarounds.

2) When recording using record~ I want to do this using an "Live press" button. I.e I want to record whilst the button is pressed down and stop recording into the buffer when the button is released. Any suggestion of an object I can do this with?

3) Same as above I want the groove~ to play only when a button is pressed and loop the selected area in the waveform~ until the button is released.

*use buffer~ intially very large, then resize when record comes to end (there are commands for this, see helpfile)

*use initially very small buffer~, record on disk with sfrecord~ then load it with 'replace' message once recording is done (probably cleaner solution)

*patch something that increase size of buffer as it is recorded. I think i saw something like this some times ago on those forums... don't remmeber, it might not have been very clean.

2) pictctrl, button, lcd, ubutton, umenu, live.button, live.tab, live.arrow

1) 3 possible solutions :
*use  buffer~ intially very large, then resize when record comes to end (there are commands for this, see helpfile)
*use initially very small buffer~, record on disk with sfrecord~ then load it with 'replace' message once recording is done (probably cleaner solution)
*patch something that increase size of buffer as it is recorded. I think i saw something like this some times ago on those forums... don't remmeber, it might not have been very clean.

Thank you for the advise and suggestions:) I also found this thread yesterday and I will experiment with varoius options. Thanks!
