The Korg monotribe is a desktop analog monophonic synthesizer with an additional three preset drums sounds. Its sound is warm and rich but quite clicky and noisy – although I think I prefer this timbre over the newer volca series. The monotribe was released in 2011 and is now discontinued.
How to Silent the VCO When Processing External Audio
The synth has an audio in port to feed external audio into 12 dB/oct lowpass filter (which uses the same circuit as the classic MS-10/MS-20). The crux is that the synth engine must be triggered to run the filter, meaning it’s not possible to process external audio solo (without being modded). But the LFO can modulate the oscillator so that it becomes nearly inaudible. The workaround below is not exactly neat, but should do the trick. On the monotribe, do as follows:
Press PLAY button and then REC.
Set RANGE select switch to WIDE and press the highest key on the RIBBON keyboard during the whole sequence.
Set EG to GATE.
Switch TARGET to VCO.
Set MODE to 1SHOT.
Set WAVE to SQUARE WAVE.
Set LFO RATE knob to minimum speed and INT. to maximum depth.
Select TRIANGLE WAVE on modulation waveform WAVE.
How to CV Control the monotribe with the Analog Keys’ Keyboard
OS version 2.11 allows the SYNC IN connection to be used as a pitch CV/gate input. This makes it possible to control the monotribe with an external keyboard or sequencer (which is great because the ribbon keyboard is almost impossible to play). There are many ways to do this, but the theory is the same: send CV and gate via a TRRS 4-pole mini jack – where gate is tip and CV the second ring.
Now I got an Elektron Analog Keys which can send both tip and ring from the same CV output, but to do that to the monotribe I’d need a special cable (sort of TRS to TRRS) and I haven’t soldered any yet. So until then, I hacked a workable cable with many different pieces I found laying around (e.g. the composite video cable was provided with a TV I acquired last year). Again, you can build this patch cable more streamlined, but here’s my solution:
Connect a composite video cable to SYNC IN on the monotribe and connect a RCA connector, white male to white female and red male to yellow female. On the other end, connect a pair of adaptors, RCA female to mono 3.5 mm mini jack male and then another pair of adaptors, 3.5 mm mini jack female to 6.3 mm jack male and plug white in CV AB and red/yellow in CV CD on Analog Keys.
While this setup only uses the tips, and demands both CV ports on Analog Keys, set CV A to Gate, V-Trig, 5.0 V and CV C to Pitch V/oct, C 3, 1.000 V, C 6, 4.000 V. (CV B and D are not used.)
Prepare the monotribe as described in the documentation that came with the download package. Activate CV/GATE mode, set the Pitch CV curve to V/oct and GATE polarity to high.
P.S. It’s also possible to create a feedback loop by feeding the headphone output back into the monotribe’s audio in. This will render a mild thickening, and if you have some kind of attenuator on the feedback signal path, you can dial in some overdrive too.
I got a reasonably priced Oberheim Matrix-1000, originally released 1987. It’s a polyphonic synth with six voices, two DCOs per voice, fully analog signal path and extensive modulation routing options – and its sound is beautiful.
But yeah, it’s a rack module and without editing options via the front panel, and it has a thousand presets and only 200 of them are editable remotely via MIDI.
The trouble with this particular item was that the fifth voice chip was broken (which I found out after buying). Moreover, the firmware running the synth was slow and contained bugs.
Fortunately someone on the internet has updated the code and they have made it available on a EPROM chip, so I ordered that. I also found a replacement voice chip and got that as well. Installing the new firmware and voice chip into the old machine was easy enough – the chips are just sitting in sockets. The voice chips counts from right to left (one to six) and are marked U101-U601.
As a consequence of scaling down my home studio, I sold two audio interfaces, Apogee Duet for iPad & Mac and Propellerhead Balance, to acquire an Apogee Quartet instead. (Yes I was checking out the newer Element 46 and even if the Element series audio quality and mic pre technology are a step above, the Quartet’s specifications are good enough for me, and more importantly I wanted/needed 8 outputs and a convenient front panel control.)
I decided for a 4-channel audio interface because I didn’t need 20+ hardware synths and drum machines up and running all the time. All that stuff took up too much space and I didn’t really use them. They were connected to a mixer – functioning more or less as a patchbay – and now that mixer is redundant. Remember, limitations drive creativity and all.
With the current setup, I’m able to insert outboard gear, not only to use Minitaur and Mopho as analog instruments, but also as signal processors/external filters. That is, with a little bit of routing in Ableton Live, I can send hardware and softsynths to the Moog ladder and Curtis low-pass filters.
Right now I got three analog monosynths (Minitaur, Mopho and SH-101) connected, and Analog Keys operating as an analog polysynth, master keyboard, sequencer and MIDI to CV converter. I can record all synths mentioned on separate tracks at once.
The plan is to switch gear depending on the project. It’s a clean, minimal setup which seems to suit me.
Recently, most time has been spent tweaking the setup, experiment with the gear, and programming and sound designing on the synths. I haven’t made any real compositions for a while though.
Next up could be a cassette tape recorder (to be able to make some lo-fi tape compression/saturation). And I think I’ll get the Strymon Deco pedal and put it in an effect signal chain.
At one point I had all gear connected, like this. That’s over 20 hardware synths and drum machines, integrated in a working and sort of intuitive ecosystem. The idea was to be ready and not having to unpack and reconnect shit, which could be time-consuming and kill inspiration in the meanwhile.
But, I tried this setup for a month, and for me it didn’t work that well. Every time I saw the pile of stuff I suffered a little from some kind of performance anxiety, I froze. It was like all this premium gear was looking at me and saying, “we’re just perfect and you got all possibilities in the world man, why can’t you produce better music? You’re not worthy.”
In spite of its purpose, the setup with all gear mounted and routed had become counterproductive. Truth is, I always worked best with constraints, regarding concept or gear, and to some extent, even budget. For me limitations do drive creativity.
Therefore I disassemble the gigantic keyboard stand and everything on it. (Also, I live in a relative small flat and a home studio like this takes more space that I can afford.) I haven’t yet worked out a storage system for all gear, but I think I put (hide) them in some drawers.
The new idea is to only have a master keyboard/MIDI controller, an audio interface, a mixer, a pair of studio monitors connected to a DAW, and then temporarily plug in the hardware I want to use for a certain project. Right now I’m working on three tracks and there are only four synths on my desk: Elektron Analog Keys, Moog Minitaur, Roland SH-101 and Casio CZ-101.
So I went to Japan for holiday. I stayed in Tokyo the whole time, which was pretty enough of experience for a first time visit.
The trip wasn’t really about electronic musical instruments, but Japan is the promised land of synthesizers (and electronics in general) and home of Roland, Korg, Yamaha, Akai, Casio, Kawai et cetera, so I just had to check up on some old vintage stuff.
I hoped to make a bargain on an authentic TR-808 but the prices where quite the same as in Sweden (around 3100 USD). Although the supply seems to be much greater, e.g. at Five G on Takeshita Street in Harajuku, they had five Prophet-5s in good condition, a couple of TB-303s and serveral MS-20s. I didn’t have room to get a full-size keyboard, otherwise I’d have bought a cheap Prophet-600.
I also went to Echigoya Music in the building on the ninth floor across from Tower Records at Shibuya, and that’s where they had the TR-808 (and a TR-909 for what it’s worth).
So I did’t buy any old analog gear, but I got a used MS2000R for around 150 USD at Creator’s Land (a part of Sofmap, on the top floor in the building where its MacColleciton is, in Akihabara). This shop didn’t offer so many analog synth from the 80s but newer stuff like Alesis Micron, Arturia MiniBrute, and they had Technics SL-1200/1210s really, really cheap.
Hard Off has a used music equipment section in one of its stores on a smaller street in Akihabara (sorry for not being more specific). I wasn’t lucky this time though, but I think that you can get good deals there.
On top of all this, Tokyo was a great city, and I can truly recommend you to visit.
In lack of a real article here’s the corner of the bedroom. Not much have actually changed sinced the last man cave shoot. (I’ve bought and sold some gear, such as another SH-101, another Juno-106 and a Kick Lancet.) The latest addition to the setup is the mighty Analog Four. I’ve also made a couple of tracks in this corner of the world. The item on the far left of the desk is a sewing machine – not mine though.
