sir.clk is a modular to midi clock interface (you’re right! CV to MIDI).
You can now clock your midi gear with your modular gates, triggers and CVs.
The interface is quite simple, there’s a “.clk” input, and a “midi” output.
It follows and adjust to the tempo of the 2 last steps.
The potentiometer controls an internal randomisation algorithm that works in the
following way:
1. when centered, the incoming clock runs unaffected;
2. when turned clockwise it increases the possibility of random clock divisions and multiplications;
3. when turned anti-clockwise, introduces jitter to the clock;
<< This makes sir.clk an interface that allows you to quickly break the boring routine of the
sequencer and his stability dogma. >>
The 3 position switch controls the following:
1.when centered, a STOP message is sent to the MIDI machine and MIDI clock message transmission is interrupted;
2.when positioned to the right, the MIDI output will run in “SAFE MODE”, which follows the MIDI standards for minimum and maximum speeds, clipping the range of your MIDI clock between 30 and 300 bpm.
<< This makes sir.clk an interface that allows you to quickly break the boring routine of the sequencer and his stability dogma. >>
It also forces a restart of your sequence (to realign the phase of the MIDI and input clock) whenever the potentiometer has been re-centered.
//THE PHASE QUESTION: the MIDI clock out will be forced in phase only in this case or when the MODE switch gets flicked to Safe or Black hole mode, it is natural behaviour of the module (and a design choice on my side) to fall in different phase positions when the input clock changes.
3.when positioned to the left, the module will run in “BLACK HOLE MODE”, this is an EXPERIMENTAL mode, has a speed limit of 3000 BPM, this depends on your MIDI machines capabilities, some machines (i.e. model cycles / octatrack mk2 / roland jp8080) can follow up MIDI messages of that speed, others don’t and stop the sequencer until you run back your clock to the “CLASSIC” MIDI limits (i.e. behringer td-3). I’ve put a limit of 3000 bpm as it seemed the max speed the elektron cycles would run before crashing.
Every time the switch engages one of the 2 modes, it sends a START message to your sequencer.

Shipping methods
All EU orders are shipped via UPS. We offer two service levels:
- UPS Standard – our default shipping option. Delivery times vary by country (see estimated delivery times below).
- UPS Express Saver – next business day delivery to most EU destinations.
Each product page shows the estimated delivery time for your location, so you'll always know what to expect before you order.
Estimated delivery times (Standard shipping)
The times below are estimates in working days from dispatch, based on UPS Standard service. Express Saver delivers by the next business day to most destinations.

These times are estimates and are not guaranteed. Delivery may occasionally take a little longer due to customs processing, local conditions, or carrier delays.
Dispatch times
Orders placed before 15:00 CET (Central European Time) on a working day are normally dispatched the same day. Orders placed after 15:00 CET, or on weekends and public holidays, will be dispatched on the next working day.
If you have an urgent order, please email us at info@signalsounds.eu before placing your order and we'll do our best to accommodate you.
Pre-orders
If a product is listed as a pre-order, it means we've ordered it from the supplier but it's not physically in stock yet. The product listing will include an estimated shipping date based on the best information we have from the supplier, but do bear in mind this is subject to change and is not a guaranteed date.
If you place an order containing a mixture of in-stock and pre-order items, we'll normally hold off on shipping anything until the pre-order item(s) have arrived, rather than splitting it into multiple shipments. If you need the in-stock items sooner, we'd recommend placing separate orders. As always, please get in touch at info@signalsounds.eu if you have questions.
