Facebook sucks. Don't know how to create a direct link to a Faceboogle article. Anyway somewhere here: https://www.facebook.com/GrpSynthesizer?hc_location=timeline is an article/entry about an upcoming GRP Synthesizer R24 sequencer.

I'll just put a quote in:

Quote:
Not only synthesizers! Here at Grp headquarters, we are creating the new R24 Analog Step Sequencer. Based on the same visionary sequencer engine previously tested on the great Grp A8 and on the mighty Grp A4 synthesizers, the new R24 expands programming and interaction capabilities between man and machine. R24 can be used in CV/Gate, MIDI and USB environment, in 8x2, 16+8 o 24 step configuration, with steps freely programmable, permutable and repeatable from front panel - independently on each row. All that was previously achievable on the old A8 and A4 Step Sequencer(s) is now available on the brand new R24, with a wealth of new - terrific - functions. Below, you'll find a first list of functions.


Grp R24 Analog Step Sequencer - preliminary info
The Grp R24 is a 8x3 analog step sequencer firmly based on the mighty step sequencer previously developed in Grp A8 and A4 Analog Synthesizers. The new R24 is full of control capability with CV/Gate, MIDI and USB connections. Hardware-wise, is stand-alone self powered, with hardware compatibility for mount on 5U module format; you can use in stand alone with its internal power, or you can install in your Dot.com/Cotk/Moon Modular system. R24 respects electrical and mechanical standards for the above manifacturers. Still, you can use R24’s own cabinet as a “presto-cabinet” for powering and using your spare 5U modules.
R24 has 128 internal memories for store and retrieve separate sequences; each sequence can be set in 8x2, 16+8 or 24 mode, with any step lenght user’s selectable.
R24 can act as CV/Gate sequencer or as MIDI sequencer, with separate rows for MIDI Note selection and for Key Velocity step adjust.
Is it possible to stack together several R24 units for long sequences in series o for more simultaneous parameter control over parallel rows.

Step Parameters. Each step has:
- CV Value freely programmable and adjustable in real time;
can be routed to Gate 1 bus, Gate 2 bus, Off (non Gate output);
- can be rythmically repeated in “Ratchet Mode” selecting X2 (simple bounce), X3 (triple bounce) or Off (no bounce);
- every bounce/ratchet mode works at double or triple speed - instant TaDream...
_can be used in Normal Mode, Skip Mode (step skipped for sequence length shortened) or End Step Mode (for define the final length of sequence)

Row Parameter. Each horizontal row has indipendent settings for:
- Glide time;
- CV Range X2, X4, X8 octave;
- Sample & Hold value On/Off (for prolonging values between contigous steps);
- Quantize On/Off (in V 1.0 you have standard semitone quantization; next firmware revision will have several quantizing masks user’s selectable);
- Six different permutation Orders selectable; for choose the playing/advance order of steps (the combinations previously available only in the Grp A4 or A8 Step Sequencer, plus several other fun modes…);
- (global) selectable Step Repetition; X2, X3, X4 repetitions before advance to the next step;
- Indipendent (full) Row Repetition (useful in chain 16+8 or 24 step mode); X2, X3, X4, infinite repeat;
- Each Row has indipendent Clock Divider; /2, /3, /4, /6, /8; divider works on Internal, TTL Ext Analog and External MIDI Clock; each row can advance at different rhythmic speed;
- Row B and C can be used with their own set of parameters in full indipendence (e.g., three different sequences in 8x3 A,B,C mode); or but you can decide to use Row A parameters over rows A and B (useful for quick program in 16+8, A+B,C mode); still, you can use Row A parameters over A, B and C (useful for quick program in 24 mode, A+B+C); buttons ON on B and C sets indipendence for Row B and C.

Row Connections on front panel. Each row has dedicated analog connection for:
- Gate Out 1 bus (internally normalled for cascading rows on single hardware connection);
- Gate Out 2 bus (internally normalled for cascading rows on single hardware connection);
First available/active step Gate out (useful for start/stop several sequencers network connected);
- End available/active step Gate out (as above, for serial connection of several sequencers);
- CV Out (internally normalled for cascading rows on single hardware connection);
- CV Control In for Order select (a specified CV received from external unit wil select the desidered Order for corresponding row);
- CV Control In for Row Repeat select (as above);
- CV Control In for Step Repeat select (as above);
- CV Control In for Clock Dividing factor select (as above);
. CV Control In for Transpose (internally normalled for simultaneusly transpose of several rows with a single connection from exterrnal analog equipment).

Sequencer Parameter
- Four-digit display for general menu parameter/value;
- Dedicated display control increase, decrease, Program and Store;
- Clock selectable Internal (with its own panel control), External Analog TTL and MIDI;
- Internal Clock PW front panel control; for adjust percentage of legato/staccato;
- Advance mode Forward, Backward, FW/BW, Pendulum, Alternate, Random;
- Sequence Mode A,B,C (8x3), A+B,C (16+8), A+B+C (24);
- Global Loop always disposable with dedicated control panel (for unconditioned sequence looping);
- Shift control on front panel;
- Row B can be assigned to Internal Clock PW Mod or Internal Clock Speed Mod;
- Row C can be assigned to Internal Clock PW Mod or Internal Clock Speed Mod;
- Dedicated front panel controls for Run/Stop, Reset at first step and individual Step Advance.

Sequencer Connections on front panel
- Remote Run/Stop;
- Remote Loop On/Off;
- Remote Reset;
- Remote Glide On/Off;
- Analog TTL Internal Clock Out (0/+5V);
- Analog TTL External Clock Out (0/+5V);
- Remote CV Control In for Advance Mode select;ì
- Remote CV Control In for Sequencer Clock Modulation;
- Remote CV Control In for Sequence Mode Select;
- Remote CV Control In for Sequencer Clock PW Modulation;
- MIDI In & Out for sequences bulk/dump transfer, for Note On/Off & Key Vel & Clock transmit;
- USB Connection for sequences bulk/dump transfer, for Note On/Off & Key Vel & Clock transmit.

Estimated time for availability: Autumn 2014
Price: To Be Announced.

For those who can read German there is also an article at Great Synthesizers:

Might also be interesting if you want to see some details.

That does indeed look like a very serious device.
I guess we will know in about a year then...
JohnLRice
Awesome! I probably wont be in a position to get one but I've long lusted for the sequencer that lives in the GRP A8! It seems to have some of the features found in the Roland type sequencers and some features I've not seen elsewhere. love

It seems near impossible to find really good demos of GRP synths. But for what it's worth here are a couple:

Christa Bachmann (synthiefrau) makes some nice demo on youtube with a GRP A8

This site is also in english smile

There a test of the GRP A8 :

anyone know if this is closer yet? my babel fish is broke
sonicwarrior
It seems the final version has been posted on Facebook (can't access the Facebook page):
http://www.sequencer.de/blog/grp-sequencer-r24-final-version/19194

Now it looks like a Dark Time XXL. hmmm.....

I want this bad.

Any info on how much it's going to hurt?
JohnLRice
lvoemachine
that looks fantastic. Really compact but still seems useable.

errmeregeerrhd

WHEN! haha
paulstone
Fantastic !
JohnLRice
For reference this is a good demo for the step sequencer in the smaller A4 synthesizer:

Wow! That looks amazing. I've always loved the sequencers in their semi-modular synths.
JohnLRice
Just putting these two pictures together to make it easier to compare since it looks like several things have changed between the initial drawing and the real thing, especially on the bottom row, like the display is one digit wider and the MIDI/USB I/O is gone. (on the back now or?)


odecahedron
anyone care to stab at a price guestimate? im guessing 1.5-2K usd ballpark
milkshake






I hope the price is below 1500 euro.[/img]
JohnLRice
I'm afraid of what the price might be . . . Tinfoil Hat . . .and how cool it might be . . . hyper

Anyone care to give a quick summary of pros/cons vs. Oberkorn and MAQ 16/3? I had an Oberkorn but its quirks finally drove me away (and my Cirklon works well enough). I've been thinking about a MAQ 16/3 for a while however to drive my analog gear in a more analog way than the Cirklon.

Dude, it's not even available yet. So we don't know which features will make it into the final version. seriously, i just don't get it

now that this seems to be closer to becoming reality, it's time to start saving away my pennies. looks amazing

In what way is the MAQ 16/3 more analog the the Cirklon ? hmmm.....

Also, the fun factor aside, what are the advantages, if any, of using analog over digital for a sequencer ?

The cirklon has much menu's than the MAQ.

If composing on a guitar, you come up with different results than when composing on a piano. Similar things happen when composing on a analogue sequencer vs daw, you come up with different results.

Yes, I know that, I used to use an MAQ, now I use a Cirklon. But this doesn't answer my question. Both a digital hardware sequencers.

I'm not talking about (ewww) a daw. I'm talking about hardware sequencers. You wouldn't believe how many times I've seen people thinking that using an analog sequencer will somehow make their setup sound differently to using a digital hardware sequencer.

The GRP A8 (or even the A4) are on my list to obtain before I die. Whichever comes first, hard to say.
