The HV-Formant synth has a total of 66 input terminals. With these terminals you make connections between the modules. On the old analog synths these connections where made with patch cabels between the outputs and inputs of the modules. (see picture)
The HV-Formant has no output terminals. All the outputs of the modules are routed to different input terminals. So if you for instance want to modulate the frequency of VCO1 whith a low frequency sinus wave from the LFO module, you select SIN1 at the VCO1 FM input terminal.
There are 5 input terminal types:
|
Control (CV) terminals The CV terminals are located on the VCO and the VCF modules and are used to control the basic pitch or frequency of the module. | |
| KEY | Midi input comming from your keyboard or VST host |
| FIX | A fixed frequency of 440Hz |
| CV1 | Frequency comming from the SEQUENCER module |
| CV2 | Frequency comming from the SEQUENCER module |
|
Gate (GATE) terminals The gate terminals are use to start the envelope curve on the ENV1,ENV2 and ENV3 modules. | |
| KEY | Gate comming from Keyboard or host |
| OFF | Switches the module off so that it doen't consume processor power |
| CV1 | Gate comming from the SEQUENCER module |
| CV2 | Gate comming from the SEQUENCER module |
| GATE1 | Gate comming from the SEQUENCER module |
| GATE2 | Gate comming from the SEQUENCER module |
| S/H | Gate comming from the S/H module |
|
Internal Signal terminals On most of the old analog synth's basic routing is fixed (internaly wired). On the HV-Formant even these signals are selectable. You find the internal input signal terminals on the bottom of the VCF1, VCF2, RFM and VCA modules. | |
| None | The input is left open |

|
External Signal (ES) terminals Next to the internal signal input terminals the VCF1, VCF2, RFM and VCA modules also have an extra input signal terminal (ES). On this terminal you can find the non regulate signals of the VCO's, VCF's, RF's and internaly generate White Noise and coloured noise. | |

|
