         (PL2) Synthesizer - English Manual

Introduction 

 

 

 

 

We are pleased that you have chosen a Ploytec 

   (

Pi Lambda squared 2

 or simply PL2) synthesizer system for your musical 

endeavors and would like to congratulate you on your decision. We’re convinced this innovative development will prove ex-
tremely useful to you in the coming years and, above all, provide you with a great deal of entertainment. 

We hope you find this manual both informative and entertaining to read, and hope you find lots of pleasure in the Ploytec PL2 
synthesizer system.
… Your Ploytec-Team! 

The PL2 can generally be powered from the MIDI port without the need for a power adapter. You should ensure, 
however, that the external MIDI device connected to this port can provide the required current. If this isn’t the case 
you can use a common 5 Volt DC (100mA min.) USB power adapter (e.g. as commonly used for mobile phones) 
and connect to the PL2 USB Micro-B port. Of course a standard PC or HUB USB port can provide the needed power 
as well.

Power supply adapter and USB cables are not part of the scope of delivery. 

Important Notes about Power Supply

At a Glance - New Features with Firmware V2.0

Now you can choose the MIDI channel and even the Omni mode (receive on all 16 channels) is available.

• 

The range of notes can be limited by min. or max. values.

• 

The startup program can be pre-selected within the editor software.

• 

If the parameter [Digital Filter Cutoff] is set to zero the key velocity will automatically control the filter cutoff.

• 

The LFO modulation effects the filter with higher speed if the parameter [Note Priority] is set 

• 

On. 

Especially for higher 

played notes the new LFO speed results in an interesting sound impression. 
Fine-Tuning is possible now. This is done by moving and holding the pitchbend wheel and simultaneously switching the 

• 

program (using the MIDI program change message) to set the new main pitch. Simply move the pitchbend wheel to the 
min. or max. position to reset the pitch to its standard value.
MIDI Active Sensing is supported..

• 

MIDI Polyphonic Aftertouch is supported. If your master keyboard or host application sends aftertouch information for 

• 

each note these will effect the volume (starting from the volume which is set by the velocity).  
Shorter program switch-over times are realized.

• 

A new Second Mode expands with three new waveforms and with the Bassdrum Mode. By using the MIDI-controller #3 

• 

(new) you can switch between the Normal and the Second Mode.  
Four new preset programs are located on the program positions 4 and 22 to 24.
