Sequencer Helper
2006-01-13 by Andrew Scheidler
Dear PSIMians - I'm fine-tuning a PSIM program that's a "Sequencer Helper". To be of use, your step sequencer must have a Clock Input that advances the step. If it also has a Reset Input as well, all the better. I use it with a MetalBox Sequential Switch and it is very cool... The PSIM inputs are: Clock (an LFO for example), the voltage output of the sequencer, and an optional Pattern Length voltage. The PSIM outputs are: Clock out (goes to sequencer's clock in), CV out (to the VCO), Gate out (to EGs) and Reset (to the sequencer's reset in) Basically it quantizes the voltage from the sequencer into a chosen number of ranges, and each range is associated with a CV (effectively quantizing the notes) and a duration measured in clock pulses. So turning a sequencer knob can change that step from an E2 note of duration 1 to a G3 note of duration 4. You can set up the notes and durations to any values you want. The first half of the knob range can be all duration 1 and the second half all duration 2, or they could totally scattered and different. Same for the notes. Mixing them up will give you new suprises everytime you alter a step. The other input tells the program how many pulses (of the input clock) to count before issuing a Reset pulse. Set for 16 pulses, it will stay with a drum machine running in 4/4 time. Set for 17 (or 11 or 21 or ???) will give you all sorts of poly-rhythmic frippy stuff. It's a blast to play with. I'll try to post the program next week along with some mp3 samples of my dinking around...

If you could give us an update ever week or every other week that would be much appreciated. thanks, phil Be sure to check out the primary Web site at: http://www.SynthModules.com Yahoo! Groups Links
