Din Sync to Release RE-303 - New Roland TB-303 Clone PCBs

RE-303 - its not a clone, its a replica

Published on Oct 28, 2015 phono1337

"more info at http://www.re-303.com http://www.dinsync.info"

It looks like Din Sync is coming out with a new DIY "replica" clone of the TB-303. There have been plenty of emulations of the 303, but only a handful of actual clones. There was the x0xb0x was based on the schematics of the original 303, Cyclone Analogic's TT-303, and most recently Abstrakt Instruments Avalon Bassline Synthesizer which I've been told has circuit boards that can be swapped into an original TB-303.

The FAQ via http://www.re-303.com:

"Ok ill start with a few obvious questions, feel free to ask more and I'll try to answer them for you.

Q: What is the RE-303?
A: the RE-303 is a replica of the Roland TB-303 motherboard and switchboard

Q: Why do we need yet another 303 knockoff?
A: There have been many clones, I honestly wanted to make a genuine replica. Now the dead TB-303's with broken motherboards can come back to life and new TB-303s can be born.

Q: Hasn't this been done already?
A: Actually no, not in the purest form. We've had the x0xb0x which sounded very close but didn't look the part. We've had the TT-303 which looks that part but is not a genuine replica of the original hardware. The RE-303 circuit boards have been made by dissecting a mint condition pristine TB-303 and manually recreating the board in CAD from the hardware rather than the service schematics. Every nuance and mistake in the hardware not in the service notes is recreated in the RE-303. It really is for all intents and purposes a TB-303. [Note: I was told the Abstrakt Instruments Avalon Bassline Synthesizer boards can be swapped]

Q: When can I get one?
A: As soon as they are ready, just post on the waiting list thread. By the nature of this project It's likely to be limited, so first come first served.

Q: What about kits?
A: This is likely to never happen sorry, this project is probably going to be the most hardcore DIY many have tried. But it will be worth the effort!

Q: What about rare parts, the VCA and CPU, memory chips, switches pots etc etc.
A: There currently exists many solutions for these today and I'm actively working on some as part of the project.

Q: How long will this all take?
A: How long is a piece of string?"

"'It's not a clone, it's a replica!'

A clone is a hardware that is made differently, with different parts and technology (SMD, OpAmp etc.) than older devices, but should sound similar. And sometimes does not sound so similar. The RE-303 ist something different, it is a replica. That means (with few exceptions) the original parts are used and also the mounting technology. In consequence there is no manual, because you can use the original manual. from the internet :)

Creating such a replica is done in handwork, because the electronic factories use more modern technology mostly. In result the device sounds like an original TB-303, I can notice the phasey trippy deepness in it, while clones are a bit shallow. But you don't have to maintain a decades old device and everything is still robust and durable.

This piece is as far as one can get to a real TB-303 because it also uses a replica of the CPU. Not all DinSync RE-303 replicas do this. (It is a sunflowr/recpu that is a replica of the CPU firmware with the same usage. More original than other choices, also in the quirks.).

The color is black and the LEDs are green, the housing is made of metal.

I used it in almost every track, but times are hard for musicians these days.

You can hear it in action in my latest tracks. Almost all have it somewhere, if there's a 303 inside, it's this unit."

DT 303 vs Dinsync RE 303


"The Dtronics DT-303 is a distortion that fits perfect with a Roland TB-303 or clone. Giving it unique sound to your acid music.

he Dtronics DT-303 is not your ordinary distortion, It is not a clone or copy.
It gives you 3 blends that you can adjust and filter. Each of the 3 settings have minor changes in the frequency spectrum. The distortion knop allows you to spice things up from minor to overrated distortion. Use the filter knob to suppress those high frequencies. A volume knob is added to adjust the output level to your needs. A bypass knop allows you to switch back to the original sound quickly.
The DT-303 was designed to fit perfect next to your TB-303 or RE-303. With the connections at the back you will have no spaghetti wires hanging over your gear."

Michigan Synth Works Chronovore 303 Sequencer running Sonic Potions RE-303 CPU

Michigan Synth Works

"This is the Michigan Synth Works Chronovore 303 Sequencer running the Sonic Potions RE-303 CPU. This will likely be a premium option down the road where you can choose the stock Pixie CPU or the SP as an upgrade. Most of the features shown here are SP CPU exclusive like the chase lights in write mode, reverse/forward play, and MIDI note play."

via Michigan Synth Works

""Chronovore is a CV/Gate Sequencer based on the TB-303. The circuit was faithfully recreated with modern components in a small form factor suitable for eurorack. The device includes the Pixie u650 CPU which runs an emulation of the original 303 mask ROM for a genuine 303 experience. Since the hardware is identical to the 303 sequencer, other CPUs such as the Quicksilver or Sonic Potions are also compatible.

Features:

Accent, Gate, CV Outputs
Clock in (24 PPQN) and Run (active High) Inputs for sync
MIDI Input for MIDI sync and start as supported on Pixie
Adjustable slide time, stock, longer, longer, and REALLY long
Digital controlled Bank/Function controls with display (pattern groups are displayed as A-D instead of I-IV)

24HP, 25mm Deep

Current Draw: +12 65 mA, -12V 0 mA"

Another one spotted and sent in via M Me.

Translated from the listing:

"The case was once planned for a RE 303 .... unfortunately I'm no longer there

The 303/606 case comes from a 606 - so no 3D printing and no TT303 housing.
I painted the part white - the new owner can still paint it.
The case is complete with battery flap and screws.

There is also an Aluminum Button Panel (purchased bought outside RE303 shop) for a TB / RE 303 and a TB 303 foil [ decal ]"

"This was a custom-built RE-303 by Raf Wlodarczyk at Michigan Synth works. I had him use custom blue and white LEDs, that are nice and diffused and not too bright, so they are easy on the eyes and look very classy. I had Raf do some other custom mods like add the ruggedized pots, so they feel really great and will last a long time. All NOS rare parts sourced. This is essentially identical to a vintage 303 minus the CPU/Midi. This unit has the rare hard to find Quick Silver CPU upgrade, not the pixie. This unit also has the designer, Paul’s, ‘dice roll mod’ which overdrives the resonance just a bit making it sound a tad sweeter to my (and others) ears. I used this one on my last album. I will miss it but already have 3 303's so need to make room for more gear."

Bass Bot TT 303 - Roland TB 303 Clone

Bass Bot TT 303 - Roland TB 303 Clone - demo 2 - Alesso - Years

Published on Oct 17, 2012 by DJjondent
I'm not seeing demo 1 anywhere so here is 2 & 3 is below.

"This is demo of a new Roland tb 303 clone.
Its called the Bass Bot TT-303 by Cyclone Analogic
Almost identical to a vintage 303 except it has presets and
midi in/out.,
CV/gate out seems identical to a vintage 303 as does programming.
Unlike all those other 303 clones out there this one could easily be mistaken for an original.
... at least in its external appearance.

more audio demos coming ...
I'll do a direct audio comparison with a real 303 soon.

Tune is Alesso's Years..... sequenced in Abelton."

How to Program a Bass Bot TT 303 - Roland TB 303 clone - Demo 3

Published on Oct 18, 2012 by DJjondent

"A quick 3rd demo of the TT303 by Cyclone Analogic.
This video covers traditional programming and play. No midi or external sequencers used this time.

If you're familiar with writing a melody on a Roland TB303 you'll probably see that the procedure is identical.

The first part of the video is standard "Pattern Play".

Then we switch to "write/pattern mode"
Here is where we write our tune.

First we need to erase our previous pattern.
Then set the number of steps (in this example its 12) .. Max of 16.
Hit pitch mode.
Write the melody.
Then into "time mode" to tell the sequencer how many notes to play.
Hit "run" to play the tune :-)

This melody is kinda boring :-( .... lets spice it up with some accents, slides or transpose up/down.

Just like the good old days.:-)"

"As Dinsync states, "it's not a clone, it's a replica" (hence the RE in RE-303).

It's a 1:1 reproduction of the original TB-303 pcbs, all the components are the same as the exception of:

- the BA662 OTA, used in the amplifier section of the synth. It has been replaced by a clone that has no notable sound difference, you can however get rid of the clicky enveloppe some 303s has with a trimmer, or leave it like this.

- the microcontroller and firmware that goes with it. It's not possible to directly "copy" the original firmware, so Sonic Potions (also known for the LXR, a DIY digital drummachine) reversed engineered the original uC to make a new one and add some more features like:

- the DIN SYNC port which originally was a 5pin DIN connector with an integrated DPDT switch (to switch between internal and external sync), so it has been replaced by a classic 5 pin DIN connector and an external DPDT switch.

- Live recording over the internal keyboard and MIDI up to 8 bars
- Realtime tweaking of accent, slide and transpose
- Random pattern generator (that can be scaled to minor/major)
- Chaselight
- All functions available while the sequencer is running
- Data storage on a modern FRAM memory

This unit has been built, calibrated and tested in July 2017 and has been waiting in a box for it's customer who finally never bought it, so it only has been used for test actually. I've upgraded the microcontroller with the latest firmware (v0.92a), it can easily be done by using MIDI sysex.

The synth is housed in an aluminium case made by Substyler. It comes with a BOSS PSA230S power supply as recommanded by DinSync, so it's a 220V euro plug. If you need a 110V PSU let me know, I'll take this one off the total price and will link you to a 110V equivalent (PSA120S should work). The power supply is really important and needs to be well regulated."

"Black metal case. Black knobs with laser green LEDs. It's a beauty... and sounds spot on as well!

I've owned a few TB-303s, as well as an Avalon and a couple x0xb0xes over the years and this 303 is the closest sounding one to the original. Absolute beast.

It was professionally made by a well trained engineer in early 2019, using original and rare parts to create the best replica imaginable. It features the Sonic Potions RE-303 CPU, which ... in my opinion, is amazing. Lots more options than the original CPU for sure."
