Doepfer POCKET DIAL MIDI CONTROLLER

via this auction
"A bit about the DOEPFER POCKET DIAL: The 4 bank buttons mean you have 64 (4x16) different MIDI controllers at your fingertips.

The rotary encoders work great (they are made by ALPS the best brand in knobs and faders) . Rotary encoders don't turn smooth as regular knobs, instead every small rotation makes a little 'click' that you can feel. The advantage of this is that when you make small adjustments, you can feel each increment/decrement so you know exactly what you are doing, you don't have to guess or see how much value change a certain rotation will result in. Another nice feature is that when you rotate a knob fast, the increments/decrements go in bigger steps, so a fast sweep ensures that the knob is in its maximum or minimum value.

* 16 high quality endless rotary encoders (alpha dials), manufacturer: ALPS
* solid silver-grey coeated metallic housing made of 1 mm steel
* measures about 25 x 9.5 x 4.5 cm
* black knobs, about 18 mm diameter, having a good grip
* distance between the knobs about 30 mm (from center to center)
* 4 banks that can be selected very fast via 4 buttons and blue LEDs (thus 64 "virtual" controllers are available)
* 32 presets (with 4 banks each, i.e. 128 presets altogether), selected via DIP switch at the rear panel
* program change button (as long as this buttons is pressed the encoder below no 8 transmits program change messages for fast preset changes of the unit controlled by POCKET DIAL)
* master channel button (for fast adjustment of the MIDI master channel, same function as Pocket Control)
* 24 detents/pulses per rotation, i.e. the data change is +/-24 per turn (if the encoder is turned slow, see acceleration)
* acceleration function, i.e. the data change increases if the encoders are turned faster
