step sequencer - interfaces
2004-03-03 by Andrew Scheidler
I am constantly thinking about the perfect slider/knob/switch interface for the perfect PSIM-based step sequencer. I wish I knew more about how a processor and the controls work together. I understand how (software wise) there can be 16 steps of 16 parameters in the PSIM, but are there limits in regards to the actual hardware controls? I'm guessing the processor constantly "scans" the various sliders/knobs/switches to check their current values, but how much does this slow down the program? Just how many controls is reasonable for a real-time hardware interface? Could a panel with 16 sliders, 16 knobs, 2x16 on/off switches be used with a PSIM? And can someone build me one right away? :) I am 100% convinced that the perfect step-sequencer (for me) is the above panel, along with a never-ending software write! Andrew
