HELP! Design Help For a Musical Instrument Program Step Changer (Not MIDI )
I have a project in which I need some assistance. (Block diagram attached )
1) I have a piece of music equipment that will allow me to step through 20 programs in a chonological manner. (1, 2, 3, 4, 5, 6, 7, etc) I can step-thru the 20 programs with a foot pedal. Each time I depress the pedal I advance to the next sequential program number.
2) I want to build a device with a keypad and a LCD screen that will allow me to send information (pulses?) to trigger the musical device,thus allowing me to punch in a number on the keypad and have it rapidly sequence through the programs and stop at the desired program.without using a foot switch.
3) I believe I may need to use a PIC so that I can program additional program changes later to incorporate additional musical devices. Is there a way to do it without a PIC?
4) I am not afraid to build this unit from scratch, so any input that you might offer would be greatly appreciated. I have been out of the electronics field for about 12 years but, believe that it will all come back to me quickly. (Associates Degree in electronics)
5) Feel free to suggest schematics, project kits or anything you have up your sleeve,
6) I do understand electronic theory, circuit building to a degree and some digital application, so don't be afraid to suggest a more advanced method. I am willing to relearn and broaden my electronic horizons.
Thank you for taking time to read my request.
