Just thinking: Does (or could) the OWL provide bus power to it’s USB, when it runs off a power supply?
Would be great to use a nanoKONTROL or some other external controller to control the OWL, that way one could have a controller on the table AND use the OWL on the ground still, via MIDI of course, e.g. [ctlin] objects in Pure Data.
Thanx for any insight.
You can supply power with the OWL, but the power dissipated on the regulator will increase. It may get hot. I wouldn’t.
But you can’t control the OWL with a USB slave (as the nanoKONTROL) because the OWL only works as slave. It has the hardware capabilities to handle OTG but is not implemented.
For this setup I use a Raspberry Pi. It has both the OWL and the controller as slaves and handles the communication between the two. This allows you to put some PD between the 2 devices and make things like arpeggiators, sequencers and all that.
Interesting approach. I just wonder, what do you need the OWL for then? Couldn’t the Pi already play the PD patches?
With an audio interface yes, but never with the OWL’s latency.
If you want to go that way take a look at Bela:
https://www.kickstarter.com/projects/423153472/bela-an-embedded-platform-for-low-latency-interact
It’s kind of a blend between the OWL and a Raspberry (actually a Beagle Bone).
Ah yes, the latency. I looked at Bela before but came too late to get one.
