Hey midiboxers, selling 2 pre-soldered GM5 chips with the small PCBs from this bulk-order: http://www.midibox.org/dokuwiki/tk_gm5_bulkorder Update: – sold. Jakob

encoders received. Thank you Wilba Kind regards koppi

Wilba, I'm in for a set.

Hm - seems, that this is my first post, so -- Hello MidiBoxers! Just finished soldering and testing the first GM5x5x5 interface: http://twitpic.com/1wdtk http://twitpic.com/1wdv8 http://twitpic.com/1wjdu Thorsten, thanks a lot for synchronizing your GM5 bulk order with the GM5x5x5 bulk order! And, Nils - thanks for designing this nice PCB! It is totally awesome. Thanks to ploytec.com for coding this genuine firmware (- can you give me a hint, how you managed to get the fifth uart work this smooth on this tiny avr chip?). Kind regards, ++koppi Update: Wrote a small linux application called "alsa-midi-latency-test" to benchmark the GM5 Midi USB interface chip and my midi setup. Here is a small screenshot: http://twitpic.com/1y188 - please pm me, if you're interested in the linux application and willing to test it with your midi setup. I need more benchmark results to see, if the app's timing results are calculated correctly. One thing, which would be really nice to test is: build a long midi chain "[PC] --> [iN1] --> [PC] --> [OUT1] --> [iN2] --> [PC] --> [OUT2] --> [iN3] --> [PC] --> [OUT3] --> [iN4] --> [PC] --> [OUT4] --> [iN5] --> [PC] --> [OUT5] --> [PC]" and see, if any kind midi message gets lost with heavy midi traffic. How is the latency in this kind of setup? Update2: Just uploaded the source of the application to github: http://github.com/koppi/alsa-midi-latency-test/ Feedback, benchmarking results and patches are greatly appreciated.
