can't get sequence length to change
#1
I've been having no success getting one sequencer to change the sequence length of another; Sending CV out to the SEQ LGTH input should alter the sequence length, shouldn't it?  I have also tried GATE out and that doesn't alter it either. 

I have set the output ranges from 5v and 9v and still can't get it to work.

I'd love some guidance.

Actually I figured it out but for the benefit of others; if you have your sequence length knob all the way at 16, the patch won't do anything; the SEQ LGTH will only extend the sequence length past where you have it set, so if you have it set on max it won't choose to shorten your sequence.

For this patch to work as intended, you will need to follow these steps:
- Turn the physical `SEQ LGTH` knob down to a value less than the maximum value.
- Connect the CV signal to the "SEQ LGTH" input of the receiving sequencer.
- Adjust the CV Signal. Start with a low voltage and increase it gradually. As you increase the voltage, you will see the sequence length start to exceed your base setting. If you are using a sequencer as a CV source, make sure its output voltage range matches the input of the receiving module

I’ve run into a similar issue before, and yeah—it *should* work when you patch CV into the SEQ LGTH input, but it really depends on how the sequencer module interprets incoming voltage. Some modules only respond to discrete voltages (like stepping between set lengths), and not all accept continuous CV. Also, double-check if the SEQ LGTH input is quantized or expecting trigger/gate signals instead of steady CV. If possible, try using a stepped CV source like a sequencer or quantizer rather than smooth CV or gate alone. What module are you using specifically? That might help narrow it down.

Good point about checking whether the SEQ LGTH input is quantized or not. Out of curiosity, which sequencer are you testing this on?

It sounds like you’re on the right track, but many sequencers don’t actually accept continuous CV for sequence length — often it’s stepped, quantized, or requires a dedicated clock/reset logic instead. The SEQ LGTH input might only respond to specific trigger values or discrete voltages rather than a smooth CV. I’d double-check the module’s manual for expected voltage thresholds and whether it wants gates, triggers, or quantized CV. Sometimes a clock divider/multiplier or a sequential switch achieves the effect you’re after.
