giro

Giro is a performance oriented (a)sync looper.

Requirements

• norns
• audio input

Documentation

Install

;install https://github.com/juhavaaraniemi/giro

General

• Loops are mono. Input is read from left input of norns.
• Master loops are cut to lenght when pressing play or stop after recording.
• Slave loops are multiples (1-8) of master loops.
• Loops are synced to master loops when playing is started.
• There can be multiple master loops within a loop group which are then asynchronous.
• Rate can be adjusted for loops and they will get async but will be synced again when stopped and started.
• There is a one step undo so it’s possible to revert to previous loop state and cancel current recording.

Screen

• white dot - selected loop
• number - loop number, suffixed by c when there is content in the loop
• status - status of loop (rec/ovr/play/stop)
• arc - loop progress bar
• vertical bar - loop level
• horizontal bar - loop pan
• m(number) - number of master loop e.g. m1
• x(number) - number of loop multiples
• g(number) - number of loop group
• G - group play enabled when visible

Buttons

• E1 select loop - Selects active loop.
• K2 rec/ovr/play - 1st press will start rec for empty master loops and overdub for slave loops. 2nd press will play loop. Next press will again overdub.
• E3 stop - Stops selected loop.
• K1+K2 enable group play - Group play will toggle group play on/off when on there is a “G” in upper right hand corner visible. In group play mode all loops within group start when one loop is started.
• K1+K3 clear loop - Clears loop contents.
• E2 loop level - Adjusts loop level.
• K1+E2 loop pan - Adjusts loop pan.
• E3 loop group rate - Adjusts rate for the whole loop group at once.
• K1+E3 loop rate - Adjusts rate for selected loop.

Parameters

• master loop - it’s possible to slave loop to another loop by selecting corresponding loop number
• loop group - loops can be grouped to loop/choke groups so that starting a loop from another group will stop currently playing group
• loop multiple - loop can be a multiple of 1-8 to it’s master loop. Note: if master loop length * multiples > maximum loop length - multiples will be reduced accordingly
• level - loop level
• pan - loop pan
• rate - loop rate (-2x,-1x,-0.5x,0.5x,1x,2x)

There are toggles for all the buttons so that they can be mapped to e.g. midi foot controller.

• record/ovr/play
• play
• stop
• stop all
• clear
• undo
• next loop
• previous loop

• group play

• save loops to disk - contents of the loops will be save to disk from buffer pre of any level,pan,rate adjustments. Loops are saved to folder /audio/giro/ in format giro_sessionidxxxxxx_saveid_yyyyyy_loopz where xxxxxx is a random number for giro session, yyyyyy is a random number for saving time and z is the number of loop - e.g. giro_sessionid489027_saveid118714_loop2.wav.

Stuff to do next

• Test & fix bugs
• Maybe grid UI for more hands on performance and less menu tweaking

Thanks

• Norns studies and all who have participated in building those
• Softcut and all who have participated in building it
• @schollz for oooooo and rc505 scripts I have been reading thru and trying to learn something
• @kbra for a couple of useful suggestions for a looper
