The VC-SPG (Voltage Controlled Signal Path Generator) is a programmable audio-matrix and a new device that uses the Ipson technology. The audio-matrix and the additional audio electronics create a powerful switching and mixing platform that introduces a new way of working for (for example) modular synth setups. The interface can be directly programmed and driven by sending and receiving OSC-messages. Within the manual you will find all the basic information that you need to work and communicate with this interface. It will explain the use of the hardware and the additional software patch (Max/Msp). Once the 32 presets are uploaded to the local memory, it can sequence through these presets by means of external triggers and control voltages.

The IpsonCompact version consists of one small printed circuit board (pcb) which is mounted on a aluminium heat-sink. It’s developed around a new version of the Microchip PIC chips, the PIC18F4423. The IpSonCompact has only one processor doing all the conversions. It has 13 analogue inputs (12 bit resolution), 4 digital inputs and 14 outputs (e.a. pwm with a 8-bit resolution). The IpSonCompact is fast. It will send all values of the analogue inputs around 1000 times per second. The sample rate is also adjustable from within Max/Msp. So if no high speed is needed, it can easily be switched. The IpSonCompact can also be configured from within Max/Msp. The sample rate can be set, the threshold per input can be set and the outputs can be configured. The IpSonCompact also has a newer version of the Xport, which has a few improvements: the web-interface improved (more clear to configure) and the host settings are extended. It is easier to send the OSC data to more computers which are not in the same subnet (so called broadcast mode).

The OSC to CV board provides 16 channels of control voltage output, with a resolution of 12 bit (4096 steps). The card can be directly connected to the IpSonCompact.

The Ipson64 is an OSC interface with 64 independent inputs. The device is designed around a PCI18f2423 chip, which has a 12bit (0-4096) resolution. The input is realised with 4 x HEF4067 chips. The communication is realised with the Lantronics XPort.
