Sequencer 1613 In details 

Sequencer 1613

VOICE 1613 sequencer can play a single track CV with 16 steps or pushing a lever, special 8 x 2 mode at 1V/Oct for dual control (eg. VCO and VCF) Each CV step can be set to a specific voltage note value of course  but also a special voltage gate on 3 gatebus  1-2-3 (upper switch)  which can be also used as an EG .  
The sequencer allow a step reset to position 1 or a skip voltage on a specific step.

Tracks A/B

2 modes:
- 1 track with up to 16 steps
- 2 tracks with up to 8 steps each. 
- Straight note playmode or   random step mode  using the relative lever switch

CV Voltage

step scale at 1V/oct with a voltage 0-10V range 
with  positive gate
- Transpose mode with CV voltage input

Dual Quantisize

2X  VCO quantisizer voltages to the nearest relative notes, much easier sequencing 12 tone melodic parts when you don't have to fine tune every step.

Clock

Internal clock with frequency or manual button for step +1 
Sequencer clock can be clocked to external triggers (patch trigger step IN)
