Doepfer A-154 Sequencer Controller Videos by Raul Pena

After Raul Pena's A-155 Analog/Trigger Sequencer videos from last month,
the only logic follow-up to that series had to be about this next module.

The A-154 is an expansion module for the A-155 that offers a lot of extra features that are not available in the basic control unit of the A-155.
Up to 2 A-155 modules can be controlled by this module.

Doepfer A-155 Video Tutorials by Raul Pena

Last week Raul Pena celebrated one year of Doepfer demo-video-creating with a nice video.
Today he is back with a new series, this time all about the A-155 Analog Trigger Sequencer.

Most Wanted II - Drum Modules

Drum-synthesizers and drum-machines have been around for a long time.
The first analogue drum synthesizers were introduced in the 1970s, and everyone remembers those classic analog and digital rhythm-boxes made by big companies as Roland, Korg, Simmons and Linn.

 The Mid-nineties analogue revival triggered a whole bunch of new manufacturers like MAM, Vermona and MFB (to name a few) to produce (modular) drum synths.
I always wondered why Doepfer hasn't come up with a modular drum series yet.
The only drumsound-providing module they released so far was the A-117 Digital noise/808 Source, a module that only produces two 808 sounds... ehh well... building blocks.

Wouldn't it be nice if you could fit a variation of different Doepfer drummodules in your rack, perhaps an A-117-X series? How about dedicated Basdrum, Snare, Hihats, Cymbal, Clap and Toms modules etcetera, with (dynamic) triggers and CV-controllable functions like decay, tune, attack and so on, so you could use any CV signal ( like from an LFO or ADSR) to change the different parameters. I see a world of interesting possiblities.

In combination with trigger-producing modules like the A-160/A-161 Clock Divider, the A-166 Logic module and/or a sequencer i'm sure modules like this could create very interesting and vivid rhythms. And how about control with one of the forthcoming touch-sensors...? Hmmmmmmm.... Want!

Doepfer MAQ16/3 and Doepfer A-100 - A Dynamic Duo

If i could only advice one external controller for the Doepfer A-100 system it would definitely be the Doepfer MAQ16/3 MIDI/Analog Sequencer.

This versatile sequencer has 3 rows of 16 knobs, and outputs a CV (for pitch) and a Gate (trigger) signal for each row. It also has a MIDI input for synchronizing, and a MIDI output to connect any sound generating MIDI device.

The ease of use of this sequencer is incredible, in just a few minutes you have different (bass-) lines wobbling through each-other...

Different running modes are available for each row, such as Forward/ Backward/ Random/ Pendulum and many more, so the possibillities are almost limitless. Other parameters that can be altered in the sequencer are First/Last step, Gate time, Tempo, and almost any other MIDI event type.

My only personal negative point that i would like to mention is the limit of 30 sequence memory spaces, way too little in my opinion, and i know it is more than what sequencers could store long time ago, but hey... can't this be upgraded to 99 memories ( please!? )

There are many alternatives for the MAQ16/3, the A-155 Analog/Trigger Sequencer is Doepfers own dedicated in-system sequencer module that can be extended with the A-154 Enhanced Sequencer Controller, but still doesn't have the full funcionality of the MAQ.

(Analog) sequencers of other brands are also quite popular, some in a eurorack module form-factor, others in the shape of desktop controllers...
