Håkan Müller, creator of the Hamu devices passed away in May 2018. He suffered from ALS for 3 years and finally decided to leave.
To honor Håkan, you can use his Rack Extensions for free from now on.
Please remember Håkan when you are inking your rack purple.

The ModSweeper lets you sweep on any knob or fader from any pair of keys on your midi keyboard.

Now you can easily modulate your filters, distortion levels etc. of your favourite devices from your keyboard. Just press e.g. key C#0 to increase and D#0 to decrease the setting.
You control the ModSweeper with any gate or trigger CV input signals, which you typically get from MidiTapper devices, but Kong or Thor can also be used, and maybe other REs too.
With a sweep time from 0.1s up to 32s, you can use ModSweeper to create slow ambient sweeps as well as fast and dramatic effects. For stepped parameters, like selectors, you should check out the twin device ModStepper.

BASIC FUNCTION

Yes, it’s one more of those CV devices and, yes, it will make it easier for you to control important parameters in your rack setup. Aimed especially maybe, at musicians who use their Reason in live performance situations.
ModSweeper primarily targets modulation of contuous knobs and faders, but can also be used for continuous controllers.

This is a CV transformation device which typically takes pulse and gate signals on the inputs and generates a continuous transition signal on the output.

TYPICAL SETUP

The typical use of the ModSweeper lets you sweep any device parameter from any pair of keys on your midi keyboard.
You can control the ModSweeper with any gate or trigger CV input signals, which you typically get from MidiTapper devices, but Kong or Thor can also be used, and maybe other REs too. The MidiTapper, however, is especially well suited to use all the features of the ModSweeper.
The output CV can go directly to the modulation socket of the target parameter, if there is one, else you use a Combinator CV input and route this in the Combinator programmer to affect the target parameter.

Check out the video for how to setup ModSweeper for typical use, using MidiTapper as a source for the modulation inputs of the buttons.
And if you are an experienced CV and cable user, I’m sure you can find other interesting ways to use this device!

FEATURES

There are three up/down pairs of buttons/inputs, which move the out level in different ways and amounts, and one knob to specify how long time it will take for a sweep between 0.0V and 1.0V (for the unipolar output).

SWEEP TIME

Defines how long time it takes to move the whole scale from end to end.
Availble settings go from 0.1 to 32 seconds.

Up and down buttons/signals:

SWEEP to move the outputs up or down at the rate defined by SWEEP TIME. Push both at the same time to immediately move output to mid point.
STEP to move the output in steps of 1/25 of the full scale by each step, equalling 0.04V on the unipolar output, i.e. 1/5 of a jump.
JUMP to move in larger steps. 1/5 of the full scale to be exact, 0.2V on the unipolar output.
