Hi,

I ve got the 555 only yesterday and here is my finding -

Usually I play some pad/pads and add to loop capture internal sounds (pad performance or d-beam synth). These new sounds adds to playing pads sounds to loop captured sample.

But it is possible to record new performance to loop capture separately.

1) for pads that will play - mfx b9 and pan to right (or left)
2) connect one (!) cable from left (or right) main out to mic hi-z input. You need to choose 1 output where is not presented sound of playing pad/pads
3) source select - ext only
4) now loop captured sound records separately of played pads.

So I have playing pads as rithm/base track and record pad performance on separate track (loop capture -> save to pad)

Hope it s useful info

oah bad^ I checked -- it works only for internal d-beam synth

now, this is not exactly what you wanted but....

there is a way to loop capture "ext only" or "ext + pads" , so you could for example record a tight 4 bar loop (on loop capture), transfer to a pad, loop/hold, then play external stuff onto loop capture (while loop is playing from pad) to keep the timing tight, then transfer that to another pad, giving you 2 sync'd up pads (1 from first loop, drums, 2nd loop from external only)

thanks for an advice
