Product Usage Instructions:

Setting up:
The CV & Gate sockets on the SH-101 are suitable for use with a CV converter. Connect the mini jack leads from the Kenton sockets to your CV converter following the provided instructions.

Playing the Sounds:

1. Connect CV Out of CV converter to CV In of SH-101.
2. Connect Gate Out of CV converter to Gate In of SH-101.
3. Avoid connecting Filter or Mod input initially.
4. If connections are correct and the CV converter is properly set up, the SH-101 will play from your MIDI keyboard.

Filter :
Filter input allows control over the depth of modulation of the SH-101’s internal LFO using an external control voltage. Not essential with most Kenton converters except for the Pro-2.

Modulation:
The modulation input enables modulation control over the SH-101’s internal LFO using an external control voltage. Typically not needed with Kenton converters except for the Pro-2.

Troubleshooting:

1. Ensure CV converter is on and set to the correct MIDI channel.
2. Check SH-101 plays without leads connected.
3. Verify connecting leads are not faulty and have 3.5mm mono jacks.
4. Test Gate signal separately to ensure note plays on SH-101.
5. Test CV signal separately by operating internal sequencer or triggering notes from MIDI keyboard.
6. Avoid connecting Filter until other functions are verified.
7. If sound stops when releasing note, check Gate output mode.
8. If tuning is off, adjust CV converter scaling to Volt/Octave mode.
9. Address any other tuning issues using CV converter controls.

FAQ

Q: Can I use stereo jacks instead of mono jacks for the connections?

A: No, always use 3.5mm mono jacks for connecting to the SH-101.

Q: What should I do if the notes played on SH-101 do not match the MIDI keyboard?
A: Check the settings on your CV converter, especially the CV output mode and MIDI channel settings.

Instructions for using a SH-101 fitted with the Kenton 2 socket kit for

Filter & Modulation (intended for use with converters which have no built-in modulation)

Setting up:
The CV & Gate sockets fitted as standard to the SH-101 are entirely suitable for use with a CV converter. The added Kenton sockets are 3.5mm mono jack sockets (mini jack). In order to connect to a Kenton converter, you will need 2 mini jack to mini jack leads for the filter & mod inputs and two more for the CV & Gate. Your MIDI to CV converter should be set up in the following way:

• CV output should be Volts/Octave mode
• Gate should be v-trig (standard gate) – where zero volts = note off and +5 volts = note on
• Auxiliary 1 should have a range of 0 to +5 volts from min to max (for filter)
• Auxiliary 2 should have a range of 0 to +4 volts from min to max (for modulation)

Playing the sounds:

• You need both CV & Gate signals to control an analogue synthesiser. The CV signal tells it what note to play (CV means control voltage). The Gate signal tells it when to play the note.
• Connect the CV In of the SH-101 to the CV Out of your CV converter
• Connect the Gate In of the SH-101 to the Gate Out of your CV converter
• Do not connect the Filter or Mod input for now.
• Provided you have connected the cables correctly, and your MIDI to CV converter is set up properly, the SH-101 will now play from your MIDI keyboard.
• Note that the SH-101 will not play notes below about MIDI note #36 or above about MIDI note #96 – this is due to the design of the SH-101.

Filter:

• Once you have got the notes playing correctly, connect the filter jack to an auxiliary output. This should be an output which gives a variable output between 0 and +5 volts – usually varied by a MIDI continuous controller such as one of the standard MIDI controllers #0 – 119 or aftertouch or velocity. Kenton converters usually have the auxiliaries assigned to controller #16 by default. As the voltage is changed from 0 to +5 volts, the filter cutoff frequency will get higher, allowing more high-frequency components of the signal through.
• N.B. The filter input is a voltage input. It is not an audio input to the filter section.
• For the Pro-Solo set Aux min to 0 and aux max to 50. For the Pro-2000 set aux min to 0 and aux max to +25

Modulation:

• The modulation input will allow you to control the depth of modulation of the SH-101s internal LFO by using an external control voltage. You do not really require this with any Kenton converter except for the Pro-2.
• Once you have got the filter working properly, connect the modulation jack to an auxiliary output. This should be an output which gives a variable output between 0 and +4 volts – usually controlled by a MIDI continuous controller such as controller #1 which is the standard modulation controller. Kenton converters usually have the auxiliaries assigned to controller #16 by default, so use the editing controls to set the control source to controller #1. As the voltage is changed from 0 to +4 volts, the modulation depth will increase.
• N.B. The modulation input is a voltage input. It is not an input for a modulated voltage.
• For the Pro-Solo set Aux min to 0 and aux max to 40. For the Pro-2000 set aux min to 0 and aux max to +20

Troubleshooting

1. Ensure that your CV converter is on and working, and is set to the same MIDI channel you are transmitting on.

2. Ensure that the SH-101 plays OK without any CV / Gate / Filter leads connected.

3. Check that your connecting leads are not faulty and that they have 3.5mm mono jacks on the end connected to the SH-101 (not stereo jacks).

4. Try just the Gate on its own. You should get a note playing on the SH-101 in time with the note played on your MIDI keyboard. It will be the same note all the time without the CV lead connected.

5. Try just the CV on its own. You will need to operate the internal sequencer of the SH-101 for this in order to trigger the notes, but the CV should follow the notes you play on your MIDI keyboard

6. Don’t connect the filter input until you are sure that everything else is working OK as with certain settings,
   the filter can stop any sound being heard.

7. If the SH-101 sounds when you release your note and is silent while the note is pressed, you have the Gate output of your CV converter set to the wrong mode. It must be set to v-trig mode (a voltage is present at the gate output when a note is played).

8. If the tuning is wrong and the intervals between notes get bigger as you go up the scale, your CV converter is set to the wrong type of scaling. It should be set to Volt/Octave mode.

9. Any other tuning problems must be addressed using the controls on your CV converter

Notes on using the clock input:

• The SH-101 also has a ¼” mono jack socket for clocking the arpeggiator fitted as standard. This can be connected to the clock output on your converter (if it has one). This will enable you to run the SH-101 in synchronization with your sequencer. In this mode, you must program the patterns you want to play directly into the SH-101 from its own keyboard. You cannot use the CV & Gate inputs for this purpose.
• When you start your sequencer, the SH-101 will then play arpeggios in time with your sequence. You will always have to start the sequence from the top as the SH-101 will not recognize song position pointers.
• For the Pro-2000, set the clock output to positive clock and the required divide rate (see Pro-2000 manual).
• For the Pro-Solo, you will need to power the converter on in sync mode. Set the clock output (aux) to positive clock and the required divide rate (see Pro-Solo manual).

Troubleshooting Clock:

1. Ensure that you are using a mono jack lead, not stereo.

2. 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 clock output on Kenton converters must receive a MIDI start command before they will output a clock signal, so if your SH-101 doesn’t start with your sequencer, check that your converter is receiving both a timing clock and a MIDI start command. You can use the analyzer mode for Kenton converters. Alternatively, you may have a faulty or incorrect lead or even maybe a faulty sync input socket on the SH-101.

3. MIDI sync isn’t on any particular MIDI channel, it’s on a sort of global channel of its own.

4. Note that 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” socket of the SH-101 will affect the LFO.
