#### like a ring buffer for audio

it's possible to create a kind of ringbuffer modula device to record some audio into the ringbuffer by triggering via gate and retrigger the audio playback via another gate
short speficication
Input:
Audio In:
Gate for Record audio in ( as long as the gate = 1 )
Retrigger In ( to start the record form the bgin of the buffer )
Output.
Audio Out:
Gate for playing the record ( as long as the gate = 1 )
Retrigger Out ( retrigger = 1 and gate = 1 start playing at the beginn of the buffer )
The modul should record as long as audio gate in is active
Ring buffer length should be setupt e.g 1/4 1/8 1/6 max 1/2 if possible ...( denpends on BPM )
The modul should play as long as gate for playing is active, retrigger via Retrigger Out
record and play back on the same time (. maybe audio play back with (one) sampledelay )
this could be funny to create new sounds from an existing loop in real time .. like beat slicing and so on
trigger the record vio midi gate sequence and play the recorded audios with a nother midi gate sequence in modular...
what do you think .. is such a device possibel .. or still existing ?

Here's Loop-lay, based on delay modules. Here's my modular patch on which loop-lay is based...
Unfortunately delay is unaware of start/stop/loop points and cannot be retriggered.

Yes, I miss something like i.e. the Roland SP 404 http://www.roland.com/products/en/SP-404/index.html or a realtime buffer sampling and retriggering like in LIZA software (only for MAC) or like Nord Modular 2 buffer module.
A 16 slot buffer, bpm sinced, with tempo selection (4/4, 3/4, etc.) and bar selection (x1, x2, x4, etc.)
It seems hard to create for my knowledge... how works rec/play in SDK???
Anyway, good point!
