It can, depending on how clever your are at interfacing it. Nick discusses one way to do it in the demo video, driving the tap tempo input on a pedal from the sequencer clock.

There's also some discussion of adding more hardware in the applications guide.

More sophisticated applications will probably involve a microcontroller, and there are more direct ways to have a microcontroller read a bunch of sliders. This rabbit hole goes as deep as you care to explore.

You totally can, check out the Theory and Applications Guide in the Documents section for instructions on adjusting the sequence length.

Thanks for the link!

I'll go talk to the folks who put the parts in the kits, and see if we can switch things so the really tiny components aren't in the same baggie as the sliders.

For anyone who didn't click through tho read it, there's also a nice demo video of the SparkPunk paired with the Sequencer in there.

Should use the trick i do for connectors. Fill in one of the holes with solder. Then heat that up and shove the part in and remove soldering iron while positioning the part. Then finish up soldering the rest of connector

First off, I take it you've seen the section that describes synch in the theory and applications guide? I take it you cut the traces on the synch port, and are injecting the new signals on the pads marked "I" that are nearer the edge of the PCB?

Also, you might want to re-check the description of the run/stop and button signals. Run and stop should be logic signals that are the opposite of each other - "run" should be high when the sequence is running, while "stop" should be low. Then when stopped, they should trade - "Stop" should be asserted, and "run" should be low. You can use a voltmeter to verify that those signals are behaving correctly.

I've looked through Arturia's documentation, and I'm not finding any description of getting a clock out of the unit. They mention CV and gate, but not clock. Do you have any links that describe external clocks you could share?

It's not stuck strictly to the SparkPunk, but (as they say in electronics textbooks) other applications are left as an exercise for the reader.

The theory and applications guide covers some of the circuit details, such as what the internal signals look like, and where you can tap them off for other circuitry.

If you're looking for a way to just hook 10 sliders up to an Xbee, there are probably easier methods. You can use an analog multiplexer to hook lots of sources to a single ADC channel, for instance.

You should also doublecheck the insides of the sliders.

On one of my pre-production kits, I thought the nut was missing. It had actually fallen through the slot on one of the sliders. Pointy tweezers extracted it.

Hah, almost the same exact thing here - I was short a 2.2kOhm resistor and the nut was also hiding in one of the sliders.

Email techsupport@sparkfun.com. They can probably work something out (like store credit for the nut so you can get a replacement with your next order). Either way its good to know, helps us keep track whether this is a problem or just a one time thing.

Yes, you can add MIDI, using something like a RedBoard with MIDI shield.

The easiest thing would be to add a MIDI input, and extract the timing clock and run/stop commands. Then it can chase external sequencers. Just inject the signals into the sync I/O port.

Going the other way, with a MIDI output, is a bit harder. If you wanted to try it, I'd set the micro up to interrupt on a pin, which would be tied to the clock output. When you see a rising edge on the clock, chek the gate. If the gate is high, take an ADC sample of the control voltage output, then convert that into a MIDI note number, and send a note on. On each new clock, send a note off, if you had previously started a note.

Slide on the CV will mess that scheme up - MIDI doesn't have a good way to represent the note changing like that. There are pitch bend commands in MIDI, but they don't have a guaranteed range.

If you really wanted to build a MIDI step sequencer, it's probably easier to take inspiration from this one, but design the hardware from scratch, with a microcontroller at it's heart.

You can change it to 8 steps if needed. Check the Theory and Applications Guide for instructions on adjusting the sequence length.

correct, updated description to make more sense.
