Author heavy duty pitch + gate sequencer module comparison
mdoudoroff
In an attempt to impose some order on the relatively-fully-featured sequencer market, I’ve begun working up a comparison chart similar to my stereo mixer comparison.

I will endeavor to keep this up-to-date. If I can make this more useful, let me know. Corrections and augmentations cheerfully entertained.

Not quite sure why the Sequins app in Ornament & Crime has been excluded. Lack of knobs/sliders? But several of the ones included don't have knobs or sliders either. O&C would also be the cheapest sequencer in that list, even as a ready-built module, and cheapest by a long shot if you DIY. Also the second smallest (only Copper Traces is narrower).

Here's a quick overview of the Sequins sequencer in O&C v1.2 firmware. It has been enhanced in the v1.3 firmware which is now available:

Great work on this, as usual. Just an FYI that Varigate 8+ has ratcheting.

Fine with me! Added. (Confession: I’m a very happy O&C user, but I’ve never even fired up Sequins. I should give it a try one of these days!)

Thanks! Fixed!

I think "tracks" is a bit ambiguous. Does that mean "channels" or "stored sequences"? Maybe change "tracks" to "channels", "outputs per track" to "outputs per channel", and add a column for "number of stored sequences"?
geremyf
Metropolis has ratcheting as well as repeat. It's nice to see a table like this where they are all on one page, and for purchasing a first sequencer it may be enough. However, more detail could be added. Things like support for din sync, slide type, max voltage (octave) range, etc.

Also, teletype should be added. According to your current columns it would be:
Shipping yes
18 hp
64 steps
4 (configurable)
1 cv/1 gate (configurable, expanders available for more per track outputs)
8 triggers/1 cv (expander availble to provide more inputs)
Ratchet / Repeat
$480
Telex/tracker

This is a cool idea! I might Twisted Electrons Cells to the bottom section since it's got similar characteristics as the René.

Another couple that could be added to the bottom section that aren't quite sequencers but designed more around interesting arp creation are the Bastl Popcorn and the WMD Arpitecht.

can teletype work without a monome?
geremyf
Absolutely. In fact, a monome cannot even hookup directly to a teletype. I don't have a monome but a teletype + telelxi expander. I bought them to control the e370 I have on order and it has been a revelation.

I'm going to get an ansible too, not for a monome but it provides a 4 voice midi to cv interface in addition to being a teletype output expander.

oh wow, TIL. I always assumed it connected to a grid with the usb in front. I was looking at teletypes, anisible, and white whales the other day and was frankly a bit confused by the product line and how everything interrelates (even more confused than I realized, I guess!)

Lol, what?

Ratcheting/repeating has a rather large focus, no? Perhaps that column should be changed to something like Grid Flexibility and then include one or more of the following:

- xox style
- ratcheting
- clock division and multiplication
- variable step and gate duration
- 4/4-only vs any meter
- and so on

And then perhaps one more column for Meta Sequencing?

- pattern sequencing
- randomization
- direction changes
- looping

What is so funny? hmmm.....

Also I like your categorization of the UI-styles. Good idea for a quick overview.

How about the sequencer's relationship with pitch?

- quantized vs unquantized
- microtonal vs chromatic-only
- user scales
Hovercraft
Nice work! Thanks. You might add the Social Entropy Engine to the external list. Also, the Fluxus One has a modulation output, arps are only one of the modulation options. It'll also output LFOs and envelopes.

Not sure if it belongs in the list but Ladik's sequencer series of modules may be of interest (which allows you to kind of build your own sequencer):

Of course there’s really no standard terminology to follow. “Tracks” is pretty common, and seems no worse than the other suggestions.

I’ll ponder the “stored sequences” idea, although that could get confusing, fast. (And I’ll add that I have yet to see a Eurorack sequencer with a compelling system for storage—this is one of my current peeves.)

It didn’t used to, but I see they recently added that feature! Will update.

Thanks. I’ll see what I can do.

I’m going to just take your word on Teletype and add it.

Everyone seems a little confused. (Monome is a company, not a product. And they’re a damned confusing company, too. Brilliant, perhaps, but confusing.) Anyway, they offer the Grid and Arc controllers. My impression is that the White Whale, Earthsea and Meadowphysics modules are all discontinued, replaced with Ansible.

authorless wrote:

I may be mistaken, but as far as I can tell, the 155 only supports gates that are the duration of the entire step. I suppose that’s a bit arbitrary (does the DU-SEQ really do “better”?) Will ponder.

I’ll see what I can do, although some of these are probably too specific or can’t really be compared reasonably.

All these sequencers support quantization except where noted. I’ll try to add something about microtonal support, though—that’s a good one.

I’m not sure either, but I’ll study it.

neonmercury1 wrote:

René doesn’t really meet the requirements because it doesn’t quite support gate sequencing in conjunction with CV sequencing. It has gate processing/filtering features, but can’t actually generate a gate by itself. I’m almost splitting hairs here, I know, but I also know René very well at this point—it’s been my primary sequencer for a couple years now.

Great work, but what about hex-inverter orbitals? And xaoc moskwa?

Maybe "tracks/channels" to distinguish it from "tracks/songs"?

Anyway, Sequins in O&C can store 4 sets of sequences which can then be chained in various ways to provide a sequence of up to 64 steps - so 64 rather than 16 steps is probably more accurate. By "store" I mean the sequences are saved to the flash memory on the module and thus persist after turning the power off and back on again.

Such comparison tables always end up being much more complex and involved than they seem at first glance, and it is impossible to keep everyone happy about what is being compared and how each data item is defined...

In typical analog fashion, the A-155 gate lengths are exactly the same as the pulse length of the incoming clock. So you can vary the gate length by changing the pulse width of the incoming clock.
Daisuk
Nice list! smile

The Eloquencer has repeats as well (as a "step mode").
justintonation
The verbos voltage multistage has independent gate length and pitch cv. Plus slew per step. And some other cool features.

Orbitals is discontinued. I’ve added Moskwa, with some misgivings. Moskwa straddles the line between a “heavy duty sequencer” and a utility sequencer (of which there are zillions). I am worried about scope creep. But for now, it’s there.

I’ve clarified the table somewhat and will continue to try to tighten it. It’s going to take a lot of work before the thing really stabilizes.

Yes, this table can never be more than a starting point. I’ve even added a caveat at the top regarding that.

Yeah, I know. I’ve added the A-155 for now, but with some misgivings. We’ll see how it wears.

I’ve added the multistage, but with misgivings. I felt doing so also obliged me to add the Control Forge. This may, in turn, oblige me to add René and god knows what else in the future. I don’t mind if it’s constructive.

I know you are focusing "inrack" but this is starting to intrigue me..

Thanks. I understand the issue of scope creep.

Pity Orbitals is no more. It was a brilliant sequencer for a reasonable price.
