Arduino Urbium Sequencer MIDI CV GATE 8 STEPS

DIY Arduino Sequencer based on the Intellijel Metropolis Sequencer

Similar projects worth following
Liked the Intellijel Metropolis sequencer so much that I made a homemade version of it. It is a 8 step sequencer with 8 pots to enter the MIDI values. Control Voltage (CV) is sent out over 5 octaves (1Volt/Octave).

- 8 STEPS (STAGES) Sequencer

- Up to 8 PULSES per STEP ( repeats the same STEP up to 8 times )

- GATE modes; 1ST PULSE, 1 PER PULSE, 1 GATE PER STEP, NO GATE ( muted )

- RATCHET; 2/3/4 equal GATES per STEP

- GATE width from 5% to 95%; Percentage the GATE stays on during the STEP 

  ( not functional during the RATCHET that is always the same )

- GLIDE; 25% / 50% / 75% / 100% into the STEP; CV voltage is gradually increased

   to the voltage level of the next STEP )

- STEP SKIPPING

- Up to 7 EEPROM memory locations ( non volatile memory ) for SEQUENCE saves.

- 5 octaves MIDI range; note 21 (A0) ( CV 0Volt ) - note 81 (A5) ( CV 5Volt )

Great project! I am not that good in programming but I think I may have a solution to implementing analog clock in.

int something = 0;

if (clockinpin=HIGH){

   step+=1;

   something = 1;

   if(step>=8){step=0}

}

if (clockinpin=LOW){

   something = 0;

}

Syntax is not exact but I think you get the idea.

As much as I analyzed the code, this should be the most simple approach.

This is neat! The Hackaday Prize has a Musical Instrument Challenge this year. You should enter this!

Here are details (you can enter it now and then opt into the challenge when it begins):
