An experiment making the Roland System 100 (MOD102) and the TipTop Audio minisystem interact in a random access melodic theme. The “S & H out” of the Roland drive the direction of the sequencer and the clock. The TipTop programmer/sequencer controls the vcos for the melody and modulations. The TipTop Z3000 vco is used as an audio source together with the Roland vco, and as a modulator for the filter and for the Roland vco. The Z3000 is used as source for the sample and hold too.
Here is a gallery of close up shots at HI-RES.

Roland TR 606 Drumatix
The Roland TR-606 was the cute sister of the great TB-303.
Roland intended to sell this pair of silver boxes to guitar players or organ players as substitutes to a bassist and a drummer.
But in the early 80s , when the popularity of sample based drum machines was growing up with the Linn drum, Oberheim DMX, Emu Drumulator, the TR-TB combo sounded really poor and unnatural to rock players who were astonished by the fidelity of the sampled sounds.
So the poor silver boxes were sold just for practicing musicians on a budget.
During the 80s many electronic bands with low budget started using both the 606 and the 303 till , in 87/88 DJ Phuture enstablished the sound of the TB-303 as a new mainstay in the dance culture.
The TR606 , often used in early new wave electro-bands became famous as a great techno drum machine, along with its bigger sisters the TR 808, TR909.
So, despite its limitation the TR606 has gained its place in electronic music appearing in many awesome records by Aphex Twin, Squarepusher, Autechre, Kid 606, 808 STATE and many more…
The TR606 is a fully analog drumsynth with a digital sequencer.
The machine has seven sounds plus accent.
The sequencer is really pretty easy to use.
It can be programmed in Step or Realtime, and is the classic 16 step TR sequencer.
You select the instrument and press the step that corrispond to the trig you want.
Really easy and user friendly!
The sequencer can also be used trig synth arpeggiators or other old machines with sync in.
The two toms have two triggers out to do it.
The 606 has a din port to sync (in or out ) with other machines that use the Roland sync 24.
The sounds are typical electronic analog sounds very close to the TR808, but with their own carachter.
The TR606 has a more aggressive and less smooth tone compared to the 808, it could be the 808 on acid!
The bassdrum kicks in a medium range, the snare is hard and snappy the hats and cymbal are really tinny, while the toms are great for that tribal electro rhythm.
This is a great analog drum machinee that’ is growing in price and popularity, I love mine and I think any electro/techno producer should own one!
This little cute box is a fully analog drumachine with a graphic sequencer.
The unit is really tiny and portable and offers six sounds plus accent.
The sounds are:
There are four knobs :
The tempo is controlled by the knob but the machine does not display the value of the BPM.
The balance act as a mix between the drum & snare and hats & cymbal.
Accent controls the “accented”sound , in fact it does not only affect the volume of the percussion accented but also the timbre.
Volume is the Master Volume.
The sounds are the classic analog drum sounds of Roland CR/TR series.
The kick is really similar to the one of the TR808 and of the CR8000 , fat and punchy, much deeper and full compared to the TR-606.
The snare is really snappy and can be a cross between a TR808 and a TR606.
Hats and cymbal resembles the TR606, while the clap is a classic tr808 one.
Programming is similar to the CR series with the pause/trig style , but is far easier than on CR78 or CR8000 because here we have a disply with the programming grid!
The display is really similar to the one on the TR707 or TR727 , all the elements are displayed and is like programming on cubase or any other software sequencer.
The START acts as TRIG and the STOP as PAUSE.
The Accent acts also as TRIG OUT INST.
The downside of this machine is the absence of a clock in , but many modifications are available to install a sync in or even midify the machine.
All in all an awesome little beast that comes really cheap!

MFB OSC 02
Yesterday I tested the MFB VCO and the MFB Dual ADSR with my Roland System100 mod 102, during the test I did some demo recordings.
The demos are quite long and in every demo I used the same “sequence” and tweaked the knobs to let you hear the behaviour of the system.
As the melody is quite redundant I hope you don’t get annoyed and focalize your attenction on the sounds.
PAY ATTENCTION!!
When you listen to the sound keep the volume at a fixed level, don’t turn up the volume when some sounds seem more quiet because there are some resonance peaks that can DAMAGE your speakers and your EARS!
Roland System100 Mod-102
As I described some days ago , I’m building a little modular in eurorack format to have a little versatile synth to make modular sounds easy, and to expand my system of vintage semimodular synths:
The Korgs work well altogether as they use the same korg “standars” as 1/4″ plugs, hz/volt , etc.
The system is well balanced and is very versatile , there are no tuning problems and connections between one module and the other has no need of attenuators and result open to every use.
Eurorack and Roland System 100 patched togheter
The Roland System 100 is quite different, it uses 3,5mm plugs, 1volt/oct and is quite difficult to make it interact with the Korgs even because the sound of the Roland is “stronger”.
After analizing different solutions (the first was to buy the other parts : mod 101 the keyboard, the sequencer and the mixer, while the second was to buy a System100m…) I decided to buy an eurorack to have a synth easier to control with computers and midi devices , more stability and however the freedom to build a synth choosing every part.
The result is, as I described, a synth with basic elements that are quite different from the “new analog” I own (DSI Evolver desktop and Studio Electronics ATC1 and SE1), but quite versaatile for a wide range of sound including FM modulations.
The first thing I tried is the interfacing between the Eurorack and the Roland and I was surprised they interact very well .
The Midi-CV interface works very well with the System100 too (I use a Kenton Pro 2000 for it, usually..).
MFB VCO (OSC-02)
The first thing I tried was to compare the Roland VCO with the MFB VCOs and I was quite surprised.
The Roland is really thick on the lower frequencies, and the square waves are awesome , but the MFB is really good too and they have a similar sound in many ways.
The MFB is less deep , especially when you hear in A->B comparison , and a little darker on the highest frequencies, but does a really a well job fattening the System100 sound without sounding different.
Roland System100 filter section
What makes the BIG difference is the Roland Filter.
Using only the MFB VCO in the roland path , with the roland VCO with zero volume, the result is amazing.
The VCO sound smooth and rich, really fat on the lower range and really harmonic and “creamy” in the higher register.
The big difference is evident in the lead sounds, they sound smooth with big carachter and warm sound without being harsh or disturbing but always rich of mid and high harmonics.
As the resonance grows the sound became quite acid (the typical roland filter carachter) but with growing harmonics, and a massive warm sound.
Then I tried to use the MFB dual ADSR to compare the behaviour of the two type of env and even here the different is evident.The Roland one is FAST and SNAPPY but always “rounded”, more musical, and gives the synth the classic Roland touch.
The MFB ENV is really fast, maybe faster than the Roland, but also more angular, with the attacks at zero makes a “ping” sound at the trig of the note.
Maybe the voltage that this env produce is higher and should be attenuated to get more musical results, even if the different behaviour is really interesting to get different result.
The first thing done was a sequenced upright bass that sounded really awesome.
Eurorack and Roland System100 patched togheter
I did the same sound using only the eurorack and the sound was similar but more enarmonic, the reason is without any doubt the different between the two filters.
Acidlab Bassline
This little alluminium box, absolutely handcrafted, comes from Germany as a clone of the famous TB-303.
Acidlab is Klaus Süßmuth, a tech head famous for his 303 modding, ith the Bassline he creates from zero a TB-clone with some variations…
let’s see the differences!
The incredible sound of the TB-303 is created by particular elements:
The Acidlab Bassline has an identical structure for the synth, with the same knobs and functions, while the sequencer is not the same as on the 303.
The knobs are really good and act smooth , they invite you to twist the sound!
The sequencer works in a different way, first it has a 8-12 selector to choose if you want a 16th note pattern or a 12th.
You cannot chhose the lenght (step ) of the pattern, for example 9 steps.
The programming is really particular because here there’s no minikeyboard, a knob switch is used to choose the note, you hit play and the bassline lets you hear the note selected, then you select accent and/or glide and /or 1octave upand than press next to go to the following step.
With this method you can get, with a bit or a lot of “randomness”, really interesting sequences without having the situation too much undercontrol.
Another difference from the 303 is that the sequencer does not change pattern at the end of the loop, but jumps immediately in the selected pattern.
This can be a creative tool to mix several pattern togheter making more complex melodies, but it’s not possible to compose a chain of pattern in song mode or something realtime like a chain of pattern.
Another interesting add is that the sequencer can drive external analog synths with cv-gate outs and can be syncronized to older machines with din sync and to a daw or midi sequencer thru midi, always with a perfect timing.
Analizing the “sound” of the Acidlab , the knobs are the same as the 303 but this machine has a kind more aggressive carachter.
It sound quite mellow when the resonance is absent, and with the filter closed can do amazing subs, while as we turn up the resonance it became acid more and more aggressive but when the reso overflow the 75% it starts sounding more industrial than the classic TB.
To change the behaviour of the resonance there is a trim pot on the rear to adjust the response , to be similar to the orginal or to have more reso.
The machine can really sound close to the original but has even its own carachter and that’s the reason why I like it!
The strange sequencer is really interesting and when you ‘ve got deep into the way it works it will be an “exclusive” creative tool.
