Synth Project

flicr set by marinedalek

"My AS Design & Technology project - a simple synthesiser built from analogue chips and digitally controlled (vaguely!)"

some info from this electro-music.com thread:
"It's a triangle-core synth based on a simple op-amp integrator design. Not having time for lots of prototyping I took the rather odd route of making it resistance-controlled rather than voltage-controlled. Each keypress on the copper touch-sensitive keyboard triggers a reed relay that switches in the tuning pot corresponding to that note. There's also a variable rate and length "sequencer" which plays each note of the keyboard in turn - by entering non-standard tunings various riffs can be programmed in.

As far as sound shaping goes, there's a PWM section with its own LFO driven by the triangle core, as well as pure triangle and square waves, with divided -1oct and -2oct square waves also included. Filtering is very basic, just two 6db/oct buffered passive lowpass/highpass combinations, which can be chained in series for stronger filtering.

Initially there were going to be two additional oscillators with non-keyboard-controlled tuning for fun swoopy sound effects, which is why I included 2 filter sections (one for osc1, the second for the other 2 oscillators). The first of these was to be a saw/pulse oscillator, and the second a sine/square oscillator - however time constraints meant these were never built

During construction a fault developed which means the output is extremely distorted (~infinite gain) with a lovely DC offset just to make it even more unpalatable. I'm hoping to fix this some time when I get some equipment set up."

"oubliettes of grief kept this one stillborn. the harvestman took it on and in the end everyone is better off for it.

i proudly sport the 'harvoks' in my modular, as opposed to my prototype.

"Sequential Circuits - Sequential MusicMate music keyboard for COMMODORE 64 . Includes floppy drive software, and original box. Cord is attached into board,(Atari type serial) And one of the floppy boxes is still covered in plastic! Board looks as if it has never been used! Box-A little worn. Disks are as follows: Model 971;song builder (Still in plastic),Model 972;song editor,Model 973;song printer,Model 974;song maker."

Note the Prophet-600 on the cover of the software.

There's a mini review up on Analog Industries.

"All I've done to this point is plug it up and take a step through roughly half the presets, but I have to say that aside from a couple UI quirks, this is an excellent box, and a really good value for your synth dollar. Quite frankly, I'd have a hard time recommending anything that makes noise that costs under $500 over this, period."

Check out the full review including some quibbles here.

Syntecno TeeBee

"Soundwise, this is the best 303 clone out there, plus it has MIDI, a ring mod oscillator, audio input, and 4 CV / gate outputs, and a MIDI merger. It is the swiss army knife of acid.

"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 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.
