ER-101: Indexed Quad Sequencer

Post by O|D » Mon Aug 05, 2013 9:40 am

I'm pleased to announce the ER-101: Indexed Quad Sequencer.

Highlights
- 4-track sequencer
- stepped and smooth voltage transitions
- each track has 3 outputs: 2 CVs + 1 gate
- each track has its own adjustable loop points
- each track contains up to 100 patterns and each pattern can contain up to 100 steps
- each step can be individually adjusted to have 0-99 clock cycles in duration
- each gate can be individually adjusted to have 0-99 clock cycles in duration with or without ratcheting
- CVs are chosen (indexed) from voltage tables of which there are 2 per track (A & B)
- built-in voltage tables: 12-tone equal tempered, 22 shrutis, linear 0-8V, exponential 0-8V, linear-exponential 0-8V and others
- voltage tables are user-editable and have 100 entries per table
- voltages between 0.000-8.192V at 1mV increments can be dialed in
- smoothing can be enabled for individual steps, entire patterns and/or entire tracks
- smoothed transitions are NOT simply slews but are adjusted to match the current tempo in real-time
- hold feature (complete double-buffering of device state) allows smooth musical edit-commit-at-will while the sequencer is running
- while in hold mode, committing changes to a running sequence can be either immediate or quantized to the beat
- reset can be either immediate or quantized to coincide to with the ending of the current track, pattern, or step
- stores up to 16 snapshots of the state of the entire device
- arbitrary insert/delete of patterns/steps with clipboard style copy/paste
- math button allows you to specify a mathematical operation to apply to a step, a pattern or a track.
- note repeat (aka ratchet) any step
- shuffle (aka swing) any step
- expansion port
- firmware upgradeable via USB

Specifications
Width: 26hp
Depth: 2cm from the back of the faceplate
Current Consumption: max 120mA from +12V or +15V
Digital Inputs: x2 (clock and reset, threshold=2V)
Digital Outputs: x4 (gates, LO=0V HI=10V)
Analog Outputs: x8 (cv-A and cv-B, 0-8.190V at 14-bit resolution or 16384 levels)

More information and ordering available here:
http://www.orthogonaldevices.com/er-101


Available in 3 different flavors: black-on-gray, white-on-gray, and metalphoto.

First Test
This is a test video showing some basic functionality while I work out the lighting and video editing flow. Warning! This is a prototype unit which had a flaw that caused the actual output voltages to be lower by about 1% from what is shown in the display. This has been fixed in the production runs.

The Faltermeyer Switch
This video steps you through an extended session with the ER-101, starting with a familiar little melody and ending up in wiggle land.

(Remember to switch to HD so you can read the labels on the modules!)
[video][/video]

How to phase it like Steve Reich
Create two identical sequences, one in track 1 and one in track 2. Pick a step in track 1 of your sequence and alter its duration by one clock cycle. This will bring the sequence out of phase slightly by one clock cycle each time the track repeats. You will get a really nice Piano Phase type of experience. Of course the granularity of each phase shift is one clock cycle, so the faster your clock is running then the finer the phasing shifts.

I love the look of this thing! Seems like a ton of functionality too.
Also, I think I prefer the white panel graphics in case you were wondering.
Looking forward to seeing some more in depth videos. Nice work. :yay:

Yep yep yep...

this looks wicked, I also agree, the grey with white print is killer, looks very military, I would assume its easy to read it in low light situations...

Keen to see some demos of it running all 4 seq at once

:eek: This is really nice!

Is it possible to backup the snapshots or patterns using the usb port as well?

woooow nice job, this is really something.

I really like the looks of it, don't change the colors!!!

Reminds me of of the yamaha dx series.. by the colors.

If something should be changed it would be the knobs, Maybe make them like the intellijel ones, you know, white on the top.

I'm set for sequencers but I love the looks and functionality of this module. With smoothing between steps you like 8 synced LFOs in there!

+ 1 it's beautiful, clever ui, much better than a roland mc4 while retaining its approach, and the user tables will be so helpfull for alternative intonations, scale modulations etc...:eek:

This looks fucking ace, I want it!

As cool as it looks on its own,I'd rather it had a shiny aluminium panel so it matched my other modules....

it really looks like a 251e, but it has:

(from http://www.buchla.com/model_251e.html)

Inter-sequencer triggering?
Variable start delay?
Retrograde capability?
Multiple nested loops?

maybe these functions can be implemented in software? :hmm:

I don't really know what much of that means :hmm:
Visually and functionally there seem to be similarities.

I'm looking forward to seeing more videos!
