RB338 versus TB303 versus TeeBee Mark III test results.
Magazine review of the TeeBee
Do you think you can make a track with your TB303 which the TeeBee can not clone ? Then mail your Audio file to Syntecno and we will post our result in the contest section.

The TeeBee is out of stock.

All good things must come to an end, and so has the production of the TeeBee. A lot of components which I used in the TeeBee have become obsolete (IC manufacturers can earn more money making IC's for the telecom business then with making old transistors for Syntecno) Also, my daytime job is consuming more and more time, and the demand for TeeBee's is not very high. All the servicing for all people who already bought a TeeBee will continue without any problem. As long as I'm alive, there's somebody who can service your TeeBee if it breaks down.

  The Syntecno TeeBee (TB303 clone)
  Model TeeBee Mark III
  - Korg MS20 ringmodulator included.
  - Full 2-channel MIDI merger ! (1x MIDI input, 2 x MIDI merge input, 1 x MIDI output)
  - Besides 5 Volt gate output, now 10 Volt gate output (Moog) also supported.

TECHNICAL SPECIFICATIONS (Mark III) (All the following modules are inside the TeeBee.)

The TeeBee is (according to most magazines and customers) the clone which has imitated the sound of the original Roland Tb303 the best. This means :
- The filter (18 dB, 2-pole) & oscillator has been made with the same components as the original TB303.
- The slide (portamento) has been fully integrated and can be controlled with a midi controller, or by using overlapping notes (AutoGlide).
- The accent function of the original has been integrated and can be controlled by sending attack velocities larger then 100.
- The TeeBee is attack velocity sensitive.

All the potentiometers of the TeeBee are able to sent and receive midi controllers.
So, you can record all the movements of the potentiometers while you are in the studio.
Afterwards, you can use these controller-trax at for example a life performance.
The TeeBee will respond to these controllers without any zipper noise or hearable clicks.

All the potentiometers can respond to any controller you assigned them to. This way you can use the TeeBee as an universal midi controller. For example, when you are using an effect processor, it's often possible to assign for example the reverb level to a controller. If you assign the same controller to a potentiometer on the TeeBee, you can now control the reverb level with any potentiometer on the TeeBee. This can be done for all 5 midi controllable potentiometers on the TeeBee.

There are 3 waveforms in the VCO of the TeeBee. (Saw, Square, Ring) The Ring waveform was not included in the original. The ring oscillator of the TeeBee is the same oscillator which is used as in the Korg MS20. The sounds produced with this oscillator are well suited for goa-trance and jungle music. More harmonics and a broader sound describes the Ring modulator.

When you want to filter your samples from your sampler (or other sound sources), you can use the analog input of the TeeBee for this. Just plug the output of your sampler into the analog input of the TeeBee. Now you can filter your samples in real-time, using the potentiometers or midi controllers with an original TB303 filter (the TeeBee). The Cutoff, Resonance, Envelop modulator and Decay potentiometers can now be used to change the characteristic of the filter. Also it is possible to 'overlay' the VCO of the TeeBee at the same time. The analog input of the TeeBee is mixable, thus enabling you to mix the VCO of the TeeBee with an external sound source and run them both through the filter of the TeeBee. This results in ultra fat sounds.

If you have older equipment which can only be controlled by CV/Gate, then you can use the TeeBee for making these devices midi controllable. The TeeBee can control almost all synthesizers of Roland, Korg, Moog and other brands. Also you can use any free CV output on the TeeBee for controlling a control voltage input on an analog synth with the potentiometers or with midi controllers. For example, the Korg MS20 has a filter control input. With the TeeBee it's possible to control the analog input with a midi controller. Now you can not only make your MS20 midi controllable, you can also make most of it's parameters (knobs) midi controllable. The CV/Gates respond fast and with good accuracy. Pitch bend information is transmitted very fast through the CV/Gate outputs in both V/Hz mode and V/Oct mode.

The midi merger which is included in TeeBee Mark III, will save you many swapping of midi cables. When you do not have several midi inputs on your computer, you would have to change midi cables all the time. This is caused by the fact that you want to be able to record from your keyboard and at the same time be able to record controllers and sysex dumps from the TeeBee. With the TeeBee Mark III, the 2 midi merge inputs will solve this problem for you. You can connect up to 2 keyboards and record midi information from them and from the TeeBee at the same time.
The midi merger in the TeeBee can also be used as a stand-alone 2-channel midi merger or for being able to control all your midi equipment at the same time from 2 (yes two) computers. Now you can control all your equipment from your ST running cubase and at the same time from your pentium running cakewalk or cubase.

The sync output of the TeeBee will sync your SH101, MC202 or TR808
Changes made to any of the setting of the TeeBee are stored in memory.
All these specs sound very cool, but it's the sound which matters most. And that's what makes the TeeBee the best from all available clones.

The TeeBee is the clone with the best TB303 sound imitation and the most accessories.

The sound comparison at the DJ terrorist page will convince you the TeeBee is the clone with the best sound.
