Prodatum as Real-time controller (Was: More Prodatum questions)

2009-08-10 by steve_the_composer

Some footnotes to using Prodatum as a real-time controller in combination with Command Station Sequencer

BACKGROUND:
Boris asked, Is it possible to have a PC sequencer and Prodatum running so that presets being edited can be heard in the context of a specific project?

I tested this out with SONAR and ended up seeing how Prodatum could be used as a real-time controller. Excerpt from previous post: 

> . . . I routed all channels on a pattern to external [Pattern Edit --> CHANNEL ASSIGN Dest:ext] from the P2500 to SONAR with echo/thru on routed back to the P2500. At the same time Prodatum is open and I can edit presets in real-time. (Now I really wish Prodatum had a panel with Controllers M-->P!!!!!!!)
 
> To isolate tracks, use mute buttons. Then edit your preset on the fly with Prodatum. When satisfied, save the preset using prodatum.

WARNING:
In a performance situation where the E-Mu sequencer is playing, do not select a new channel or a new preset. This will cause a whole batch of data to be sent to Prodatum causing the E-Mu sequencer to hiccup or spasm. 

CREATIVITY WITH ARPS:
With Jan's arp editor, you can "play" an arp in realtime. Turing end points on and off with a latched arp adds a new dimension to arp seqeuncing. WISH 1: assignable hot keys (PC keyboard, external controller, both) to program arp edits on the fly. WISH 2: multiple arp windows--maybe even enough to play E-Mu's 32 arps at the click of the mouse in my right hand and selectable arp editor focus from the PC keyboard in the left hand (if they all can't be in focus at the same time). (This would really unleash some of the untapped power in the non-Command Station P2K-based synths.)

You can really do some juxtaposition of odd meters just by turning those end points on and off as your pre-recorded patterns play. 

BTW, if you try this at home (specifically, routing a Command Station sequence's tracks externally through a PC sequencer which in turn echos the sequence back to the Command Station and then playing arps real-time via Prodatum), make sure arps/riffs are NOT being transmited externally.
