Have just uploaded some Sequetron Tutorial videos to YouTube. They show a few more things not apparent in the original video a couple of years ago.

Original: http://www.youtube.com/watch?v=gR66Lk2x4UM

Recording sequences: http://www.youtube.com/watch?v=8y0tOGMCAW4

An interesting side issue came up when I was trying to video it this time, as the monitor screen is no longer next to the MIDI keyboard so I couldn't video both in one take.

Having discounted a 2nd camcorder or using mirrors, I realised that as the Sequetron is driven purely by MIDI.... why not record the MIDI input stream onto a sequencer while videoing the keyboard, then play it back into the Sequetron to video the screen activity? The two videos could be merged later using an editing package.

I was using a Korg i30 as the MIDI keyboard, so put it in Song mode and pressed Record while I ran through the tutorial pieces. Then I re-positioned the camera and pressed Play on the i30 (no MIDI re-wiring was required as its output already went straight into the Sequetron).
I don't know why I didn't expect it to work - it's pretty obvious it should Rolling Eyes, but it seemed strange to have the Sequetron running on its own.

It then struck me there may be some possibilities for composing with this input MIDI 'meta-language' (Sequetronese?!).
This would be dependent on the key-mapping you use, but in my case the following notes are all you need to generate two arpeggiated sequences which would run forever:-
C Gb Eb <sequence1> Db C G Eb <sequence2> Db

To pitch shift up 7 semitones and back again, just add:-
C D1 G1 <pause> C D1 C1

The next logical step is to merge its output back into its input and stand well back.... Shocked
Phil.
