GMS Practice Track Number 3

Posted on May 11, 2009 by John C.S. Keston

top_lights I’ve almost finished with my initial round of tweaking and bug fixing on the GMS, so I’ve finally been able to put a bit more time into actually using the software for its intended purpose. My most recent work with it involves a companion document in Ableton Live that loads a number of virtual instruments into about nine separate MIDI tracks. Ableton provides the external sync via the Apple IAC (Inter-Application Communication) drivers. In turn, the GMS sends MIDI note on and off data to the instruments in Ableton. Using this method I can live loop on various tracks and build a multi-timbral composition in real-time. Here’s an example for a recent practice session.

This recent practice session illustrates the use of external sync and live looping of MIDI data captured from the GMS in Ableton Live.

Here’s another sample of a practice session using the GMS and Ableton Live.

GMS Performance in Downtown Minneapolis

Posted on May 8, 2009 by John C.S. Keston

I’ve been scheduled to perform live using my GMS this Wednesday night, May 13, 2009. I’ll be projecting against the Western wall of Art Institutes International. The reactive music will be amplified along with the projection as it is produced in real-time. Here’s the publicity statement that went out about the event.

John Keston will be performing using his gestural music sequencer or GMS on Wednesday, May 13, 2009 in the parking lot next to Art Institutes International Minnesota, 15 South 9th Street, Minneapolis, Minnesota. The GMS was written in Processing.org by Ai instructor, Unearthed Music recording artist, and AudioCookbook.org founder John Keston. His tool analyzes video input and converts it into a sequence of musical information in real-time. The live video image will be projected on the building while the musical response to the images is amplified through a sound system. For more information about the GMS visit audiocookbook.org/tag/gms/. All Ai students, staff, alumni, and the public are welcome to attend this free performance. A drawing will be held (for WDIM students only) giving away two passes to this years Flashbelt conference.

Here’s a segment from a practice session today to give you an idea about what sort of output the GMS can produce. All of the percussion, melodic lines, and bass were generated by the sequencer, then live looped to produce the results.

Microtrack of Recycled Rhodes, Beats and Bass

Posted on May 7, 2009 by John C.S. Keston

Lobby Lovingly mixed on cheap ear buds, this micro track consists of a cut up chunk of low frequency Rhodes running through auto pan and a bit of amp modeling, out of key FM synth bass, and frosty beats that were partially programmed using the GMS (Gestural Music Sequencer). It’s not a habit of mine to mix blind (or would that be deaf?), so I hope there aren’t too many nasty surprises when I hear this through proper speakers.
