Discontinued Systems

Cost: $198 US
Connection: MIDI
Inputs / Outputs: 32 / 8
Signal Bandwidth: 24 – 244 Hz (depends on number of I/O pins in use)
ADC Resolution: 7 or 12 bit
Power: external 7.5 V supply
Sensors are generally purchased from Infusion Systems, at significant cost.
Programmed from a host computer via MIDI system exclusive messages (Windows, OS-X, 3rd party Linux).
Can save settings for “stand alone” mode.

Cost: $111 US
Connection: MIDI
Inputs / Outputs: 8 / 0
Signal Bandwidth: 1500 Hz
ADC Resolution: 7 or 10 bit
Power: external 7.5 V supply
Sensors are generally purchased from Infusion Systems, at significant cost.
Programmed from a host computer via MIDI system exclusive messages (Windows, OS-X, 3rd party Linux).
Can save settings for “stand alone” mode.

Cost: $50 and higher US (cheaper in quantity)
Connection: serial (or USB-to-serial interface)
Inputs / Outputs: 16 (32 on BS2p40)
Signal Bandwidth: depends on output serial port speed
ADC Resolution: No built-in ADC but supports 16-bit math
Power: external 5 – 12 V DC supply (can be battery)
User must buy and design own sensor circuits
Programmed from a host computer via serial interface
Output via MIDI protocol is typical (with speed and bit limits)
Can save multiple programs in “stand alone” mode (on models with scratch pad RAM).

Cost: $99 US
Connection: MIDI
Inputs / Outputs: 10 analog inputs, 20 digital inputs/outputs or analog (PWM) outputs
Signal Bandwidth: 4000 Hz
ADC Resolution: 10 bit
Power: 9 V battery or external 9 V supply
Sensors are not sold by Eroktronix ... they must be developed by user.
Programmed from a host computer via MIDI system exclusive messages.
Can save settings for “stand alone” mode.
Oriented toward use with Max/MSP.

Cost: $295 US
Connection: S/PDIF (RCA or TOSLINK optical)
