EHX pedal based analog sequencer

so maybe the lfo square wave patched through a mult on the 351 to gate input on the voyager and the input on the ehx? this gives me some hope…

The EHX pedal does not seem to have a Gate in to advance the clock; only works off Midi I think. So if Voyager can send Midi clock, I’m sure you’ll be able to gate notes internally or via VX-351 back to ENV Gate in while sending clock to the EHX 8 step.

If Voyager doesn’t send clock, I’m sure you can send it from your DAW or from a drum machine to both Voyager and 8-Step.

Again, poor Old School owner here, not completely familiar with the digital capabilities of the Voyager so the major assumption is that you can sync the internal LFO to Midi Clock. Little Phatty has menu options for clock divider which runs LFO or Arpeggiator but no way that I know of to take the clock and gate envelopes except according to ARP keys. Certainly, CV in can ‘fight with’ the note stack in the ARP sequence and certainly you can send the LFO destination on Phatty to Envelopes as you can Voyager but opening and closing the Filter cutoff according to a fixed shape of the LFO is very different from gating the envelope that might have a really nice Decay, etc.

(stating the obvious here)

An analog sequencer without a gate signal output is pretty useless… Gross oversight on the part of EHX IMHO. :confused:

Hmmm… I don’t know: EHX claims it’s a control sequencer for other effects more than an analogue sequencer in the synth tradition. Kind of an automated expression pedal.

I think it’s consistant.

Perhaps. But would it have been so hard to add a $0.50 trigger output jack, don’t you think ?.. :unamused:

They could have reached another market (analog synth enthusiasts), and raised the number of sales of the device accordingly, simply by offering trigger/gate out !

Marketing mistake, I guess.

If only it were that easy…

Actually, with today’s digital programmable technology, it is… Because even though this is touted as an “analog” sequencer, it isn’t really. It’s a “virtual analog” sequencer using a programmable DSP (most probably an Analog Devices BlackFin processor, as in all of the other recent EHX effect pedals) to keep production costs way down. In which case, a couple of lines of additional code, along with an op amp buffer with an output jack, could probably do the trick for a gate/trigger out.

As seen here, inside another EHX pedal (Hog2 Foot Controller):

Mine arrives shortly.

For those lamenting about no analog clock in, you are in luck. The external CV in can be configured for several uses including sync to external analog clock.

I will mainly be using mine to control filter cutoff on my modded x0xb0x. I am sure it will also be pressed into action with my LP as well.

Someone over at Muff’s forum has figured out a gate out mod…

Looks relatively easy, if you are handy at soldering.

Arrived yesterday.
Don’t know if I’ll need the gate out mod. Nice that it is relatively easy. Looks as if it existed at some point in the design.

The white plastic buttons feel cheap, don’t think I’ll use them much though. Stomp switches are very easy to finger push, no click! Sliders feel okay (as always more travel would have been nice). Push encoder feels very solid for a push encoder, time will tell (love the functionality, hate the inherent durability issues).

I was excited by all the midi CC control, but after a short session I do not know if it will be used as anything but an LFO. So much fun! Drawing wave-shapes on the fly and tweaking depth, rate, and glide. :smiley:

I still need to test for zippering with very slow glided sequences. I expect to find it at some settings.

New video:

I just got the 8 Step and am trying to use it with my Minitaur but the signal is passing through unaffected. I can’t get the 8 Step to do anything with the Minitaur signal whatsoever. Is this because of the gate issue? Is there anything I can do or should I return it and save for a Doepfer Dark Time?
Please help!!

What parameter are you trying to sequence with it?

Try triggering notes with midi (external sequencer or keyboard) and using the step 8 to modulate the filter. The minitaur only responds to CV from 0 to +5V; so, moving the sliders below the mid line will not do anything. Also, make sure the depth on the step 8 is turned up (zero depth will produce 0V on all steps regardless the slider position).

This video is disturbing!

If by gate issue, you mean that 8 step does not have a gate out. Then you are correct.

But that doesn’t mean that you cany use it. You’ll need to actuate the gate and hold it, and this can be done by holding a midi key or using the dummy plug method published elsewhere.

You won’t be able to craft the timbre because the Env generator will not trigger but you can run midi clock in then sync the minitaur LFO to midi clock and have it pulse in time with the stepping.

The minitaur LFO is a sine/tri wave so not the best, but it’s something.

One other somewhat unorthodox solution is to pump a hard hitting bass drum sound into gate. Ideally, have your drum machine send midi clock.

Don’t give up!

Droner, as described in the dedicated topic, here is what you can do with your Old School, her VX and the EHX 8SP:

Sooo…

I had a session yesterday with the EHX 8SP controlling the pitch of my LP, which was feeding the previous for MIDI clock.
I kind of bugged the thing: Tap Divide LEDs all lit, but no way to cycle the setting. I lived with it for a session, and decided to consult the manual again later.

Tonight, I’ve done so and I found nothing explaining that. I did not even find why holding teh Tap Divide button would lit two over three MODE LEDs…
Anyway, I had to Factory reset in order to attempt to reproduce that weird behavior. It seems the MIDI CC#29 sets the tap divide parameter… and makes the box bug: I could see all kinds of characters on the display when turning the MODE encoder, sometimes going with not less weird sounds.

Has anybody experienced anything similar?
