Mutable Instruments Frames - Manual (Page 2)

About Frames
Frames brings to Eurorack modular systems the con-
cept of keyframing, widely used in computer animation.
It allows up to 64 configurations of gains (or control volt-
ages) to be stored and morphed into one another.
Mix, pan, morph, dispatch or control four channels of
sounds or CV!
Installation
Frames requires a -12V / +12V power supply (2x5 pins
connector). The red stripe of the ribbon cable (-12V side)
must be oriented on the same side as the “Red stripe”
marking on the board.
The power consumption is as follows:
-12V: 30mA; +12V: 90mA.
The jumper at the back of the module selects the con-
stant voltage sent to unconnected inputs (+5V or +10V).

Walkthrough
Power on the module. Connect two different audio
sources to channel inputs 1 and 2. Listen to the MIX out-
put. In this configuration, Frames works like a mixer.
Turn the FRAME knob fully counter-clockwise. Press
the ADD button. Using the first two knobs on the top row
(labeled 1 and 2), mute channel 1 and set channel 2 to
maximum level.
Turn the FRAME knob fully clockwise. Press the ADD
button. Mute channel 2, set channel 1 to maximum level.
What happened? You have created two keyframes, each
of them storing a different configuration of the channel
gains. By moving the FRAME knob, you can interpolate
back and forth between them. The FRAME knob is like
the play-head moving through an automation curve.
Move the FRAME knob to the middle position. Press the
ADD button. Set the two channels to their maximum
level. You have created the animation shown here:
Send a LFO to the FRAME CV input and adjusts its
amount with the MODULATION attenuverter to move
through the animation.
Signal flow
Frames is not just a mixer. It is actually comprised of
four digitally-controlled analog VCAs with DC coupling.
• Each VCA has an individual input and output.
• When no patch cable is inserted in a channel input, the
signal from the ALL input is processed instead.
• When no patch cable is inserted in the ALL input, and
if the +10V offset switch is on, the ALL input receives a
constant 10V CV. Sending this constant voltage into a
VCA turns it into a CV source! This voltage can also be
set to +5V with the jumper at the back of the module.
When no patch cable is connected to a channel output,
the signal is sent and summed to the MIX output.
