PLEASE NOTE: Fitting a socket upgrade kit is a skilled job which should be undertaken only by a competent synth service engineer or fitted by us at our premises in South West London.
Kit to add a filter socket to the Roland SH-101
This synth already has suitable CV and Gate sockets, so it is not necessary to add them.
This additional socket will enable the cutoff frequency of the low pass filter of the synth to be voltage controlled. This can be acheived using an aux output of one of our MIDI to CV converters, such as the Pro-Solo mkII or Pro-2000 mkII. You can then control the filter cutoff using any continuous controller (cc) or other MIDI messages such as Aftertouch or Velocity.
The kit contains all necessary components and diagrams for connecting the wires / components, and mounting the 3.5mm mono jack socket.
Kit to add filter and modulation control sockets to the Roland SH-101
This synth already has suitable CV and Gate sockets, so it is not necessary to add them.The additional sockets will provide:
A voltage control input for the cutoff frequency of the low pass filter of the synth
A voltage control input for the modulation depth of the SH-101’s inbuilt LFO.
Control can be acheived using the Aux outputs of one of our MIDI to CV converters, such as the Pro-Solo mkII or Pro-2000 mkII. You can then control the inputs using any continuous controller (cc) or other MIDI messages such as Aftertouch or Velocity.
The kit contains all necessary components and diagrams for connecting the wires / components, and mounting the 3.5mm mono jack sockets.
Note: All Kenton converters (except the discontinued Pro-2) have MIDI controllable / MIDI syncable LFOs built in, so unless you have a Pro-2 you only really need the filter socket only version of this kit.
It is not possible to synchronise the speed of the internal LFO of the SH-101 – use the LFO inside the converter.
The SH-101 already has CV & Gate sockets which are suitable for connection to a CV converter. We can supply a 1 Socket upgrade to fit your SH-101 with a filter input socket or a 2 Socket upgrades with a filter and a modulation input. The modulation input allows an external control voltage to set the depth of modulation for the internal LFO. N.B. Although the internal sequencer of the SH-101 takes its speed from the LFO, this does not mean that connecting an external clock source to the EXT CLK IN of the SH–101 will affect the LFO.
- You need to make sure that the clock output is enabled on your sequencer, this is very often on a setup page or on a pull-down menu. The sync 24 output of Kenton CV converters cannot be disabled, so if your TB-303 or MC-202 doesn’t start with your sequencer, you can be sure that the CV converter isn’t receiving MIDI sync (see note 4) or you have a faulty lead (see note #2) or even maybe a faulty sync input socket on the TB-303 or MC-202.
- The lead you need for connecting the sync 24 output of the CV converter to a TB-303 or an MC-202 may look like a MIDI lead, but it is not. MIDI leads need only 3 connections out of the possible 5 on the 5 pin DIN socket, the sync connection requires that all 5 wires are connected, which means that the majority of MIDI leads won’t work. You need to get a standard 5 pin DIN to 5 pin DIN lead which is readily available or Kenton can supply.
- You need both CV & Gate signals to control an analogue synthesizer. The CV signal tells it what note to play (CV means control voltage). The Gate signal tells it when to play the note.
- MIDI sync isn’t on any particular MIDI channel, it’s on a sort of global channel of its own.
- A MIDI to CV converter, converts an incoming MIDI data stream into control voltages of various kinds for connecting to synths with suitable inputs. A CV converter does not convert the analogue signals back into MIDI, you would need a CV to MIDI converter for that.
- References to filter control, mean control of the filter cutoff frequency, sometimes also called filter sweep or VCF frequency control (VCF means voltage controlled filter).
