"the metropolis is a unique and powerful musical sequencer inspired by the ryk m-185 (a roland system 100m format sequencer.) but with many additional enhancements and functions.

the metropolis comprises eight "stages", each with its own assignable gate mode, pulse count and pitch value. each stage can also have a special slide or skip function activated too. the slide functionality is a constant time portamento very similar to the roland tb303 (unlike most synths/sequencers that use constant rate portamento) which produces a very musical and interesting result.

in addition to the base sequencer settings set with the sliders and switches there is a full menu of controls and auxiliary modifiers that allows the user to control and manipulate the sequence in many powerful ways including sequencer direction modes, pitch quantization and scale manipulators, clock dividers, shuffle and much more.

some of the features :
sequencer modes:
forward, forward-fixed, reverse, reverse-fixed, pingpong, pingpong-fixed, random, random-fixed, brownian, brownian-fixed
tb-303 style slide (constant time portamento) with adjustable time
stage skipping (double click slide buttons)
internal quantizing in any key and a choice of 30 different scales
can act as a master clk with tap tempo bpm control or slave to an external clock (with bpm detector)
save/load panel settings to eeprom
shuffle
internal clock divider with odd/even/all modes and can also be used to sync stage changes
sync output (sets output pulse on the first or last clock step of a sequence, used to slave other sequencers via reset)
two assignable aux inputs which can control: gate length, transpose, key shift, root shift, sequence length, step divisor and octave offset.
config menu to set slider pitch range, clock div type, sync type and reset type
all menu actions are one level deep. i.e. press the menu button and spin the encoder. there are no hidden levels or sub menus (except for the config menu_
all the core original m185 functions are there too. read more here
user replaceable firmware chip

Intellijel Metropolis Sequencer Based on RYK Roland System 100m M-185

Metropolis Scrutineering from DUDADIUS on Vimeo.

"First go around with the Intelljel Metropolis. This is a pretty basic setup; I didn't get into using the aux inputs to modulate things within the Metropolis. I'll try that next! As you can see though, the Metropolis really lends itself to performing and improvising. Very hands-on and easy to go all sorts of crazy ways, melodically. Similar to the Rene, in that regard, but from a totally different point-of-view.

Patch notes. Pamela is sending clock to Metropolis, Trigger Riot, Modcan Dual Delay, and Sound of Shadows.

Metropolis is sending the same note info to three different oscillators. The third one going through a uScale first to create intervals. All going into the Dubmix. The Trigger Riot is controlling Tiptop drums, mixed through a VCA Matrix then an M277 for a little grit. That's into channel 2 on the Dubmix, where I add a little Spring Reverb at one point.
The kik and snare are ultimately doubled with the Cwejman BLD and DPO. Lastly, I dialed into some sustained notes on the Pressure Points and a Modcan Triple OSC. The uStep is advancing the Pressure Points.

I had some troubles with the Trigger Riot losing sync when I would change presets. I'll have to delve into that some more."

Note the RYK M-185 was a DIY sequencer from RYK, not Roland. See the RYK channel below for more.

Regarding the Intelijel Metropolis, the following is some info via PatchPierre.Net, via Pierre on The MATRIXSYNTH Lounge

"One of the most interesting modules i have seen in a while has been sent out to various testers in the last few weeks. The Intellijel Metropolis is a Eurorack sequencer, based on the RYK M-185 sequencer from the early Roland M-100 series. This module has always intrigued me, and i was always hoping someone would bring this style of sequencing/programming to the Eurorack. Intellijel worked out an agreement with Ryk earlier this year to create this only official Eurorack adaptation of his brilliant sequencer design...

Some of the features :
-Sequencer modes:
Forward, Forward-fixed, Reverse, Reverse-fixed, PingPong, PingPong-Fixed, Random, Random-fixed, Brownian, Brownian-fixed
-TB-303 style slide (constant time portamento) with adjustable time
-Stage skipping (double click slide buttons)
- Internal quantizing with selectable scales and keys
-Can act as a master clk with BPM control or slave to an external (using clk src function)
-Save/load panel settings
-shuffle
-Internal clock divider
-Sync output (sets output pulse on last clock step of a sequence, used to slave other sequencers via reset)
-Two assignable AUX inputs which can control: gate length, transpose, key shift, root shift, sequence length, and step divisor.
-config menu to set slider pitch range, clock div type, clock offset
-tap tempo when in internal clock mode and tempo lock with bpm detect in external mode.

-All menu actions are one level deep. i.e. press the menu button and spin the encoder.
There are no hidden levels or sub menus."

Megawave Quantizer ROM

Published on Aug 12, 2013 buriedintime·48 videos

"Malekko/Richter Megawave quantizer ROM.

deopfer LFO clocking a synthwerks PGM 4x4 output to deopfer sequential switch to get 8 steps (can get 16 but for this purpose 8 notes are plenty) CV out of the switch to the megawave.. out of megawave into CV in of bubblesound vcob.. audio = saw wave to tiptop Z2040 filter to intellijel linix VCA.

some modulation happens later via Livewire Vulcan Modulator and row 4 of the pgm 4x4.

this patch is just to show some of the quantizer scales in the quantizer ROM of the Megawave.

"This is a highly versatile and very musical device for creating interesting, beautiful and harmonious musical riffs from just about any analog cv sources. Please see the demo videos to get a taste of some of the creative things you can do with this module.

Features:

12 buttons with matching dual color leds for selecting scale notes in real time (and visual feedback of quantizing).
Processes 0-10v (as 1v/oct) in the ‘in’ input.
Accepts 0-10v or ±5v on the ‘shift’ input (jumper selectable) for a shift range of ±12semitones or ±12 scale degrees.
Two 0-10v outputs (a and b) with 1v/oct scaling.
Output b is a user selectable interval based on the root note on output a. this interval can be chromatic (fixed semitones) or diatonic (interval is within the current scale and the value is based on scale degrees). this interval can be a bipolar value of ±12.
Shift has user selectable destinations of note a, b, a+b or the scale root.
Shift has user selectable modes of where shifting occurs: before scaling, in scale (diatonic) or post scale (key shifting).
Menu for shifting the scale root manually.
Special ‘scale shift” mode allows the “shift” input to select scales from the current bank (so 12 scales can be selected by cv).
Can store 12 scales in 12 banks for a total of 144 different user scales.
Module ships with 5 banks preloaded with scales (they can be erased by the user and reprogrammed).
Precision trimmers on pcb for fine tuning and scaling the two outputs.
Skiff friendly depth
uni/bipolar cv switch added to the panel
16bit super low INL error TI DAC which translates to +/-0.0005V accuracy for pitch CV."

Introducing the Intellijel uMod, uAtt and uScale

"uAtt: 4hp quad passive attenuator. Has jumpers to select log or lin response.

uScale: 4hp quantizer and intelligent interval module
-buttons to select scale notes
-duo leds show scale pattern (red) and realtime quantized note (green)
-Special multifunction "shift" input operates in range +/-12 semitones. Jumper on pcb to select 0-10V or +/-5V interface.
-With shift you can alter the output in multiple ways including: transposing before force to scale, transposing in scale (e.g. a value of "4" results in the note transposed 4 scale degrees instead of 4 semitones) and post scaling which allows very interesting key changes. The shift destination can be routed to the main noteA, interval note B, both or the scale root (again creates really interesting scale changes). Output B (interval note) is derived from the root note. It can be selected as +/-12 semitone value.
-interval note can also remain chromatic (not forced to scale) so that you can have fixed intervals. Nice for FM perhaps.
-8 banks x 8 scales of store/recall
-manual scale root note shifting (essentially shift scale left/right)
-** in process of adding a scale select mode via shift input
-This thing makes anything sound musical!!!


uMod
-this is the first of a series of collaborations with analog guru David G. Dixon and based primarily on the SSM2164 quad VCA chip
In his words:
Quote:
It’s a ring modulator with a twist. It’s got a “Q Balance” knob which puts it into four-quadrant multiplication in the middle, and – or + two-quadrant multiplication at the left and right. The X and Y inputs also have rectifiers which pass the –, –/+, or + portions of each signal with the flip of a switch. This, along with the adjustable multiplication, gives a whole range of sonic possibilities not generally available from ring modulators. It also makes a wicked waveshaper as well as a very interesting CV mangler. See the attached document for some random scopeshots (will post soon). AC/DC coupling switches on each input add to the possibilities. Plus, since it’s based on opposing linearized 2164 VCA pairs on the same chip, it is very accurate and has almost no CV bleedthrough (unlike most ringmods).

Special thanks to Haven, James Cigler, and Shawn for great input on these modules.

These three are in production and price/ship date will be announced soon. uScale takes more work since it requires programming and calibration but I am working 24/7 to get some units shipped before x-mas (even if it is a small batch)."
