MiDi TRANsfeR of PReseTs
If you press
BOTH
the SAVE and the LOAD buttons at the same time the
PRESET MODE edit page will be displayed. This mode allows you to read from, or write to, the preset memory
from an external computer or MIDI-capable patch storage device. When first entering this display mode, the
display will show the “Connect USB ^” message. This refers to the USB micro connector on the top of the
display board at the rear of the module. You will have to remove the module from the case to connect a USB
cable to it. The power should still be connected, however. Connect a USB cable to your midi storage device
(typically a computer). Once successfully connected (your computer may have to install the proper drivers
first), the display will change to read “USB connected Waiting for SysEx”. SysEx is short for “System Exclusive”,
which is a special type of MIDI message used to transfer patch data (among other things). You will need
software on your computer that is able to send and receive patch using SysEx data transfers. There are many
freeware software packages that can do the job. On PC compatible computers the program MIDI-OX is good for
this.
The MIDI SysEx command strings for sending and receiving MIDI preset data are as follows:
To
download
one preset (from the Rainmaker module to the computer):
0xF0, 0x00, 0x02, 0x14, 0x01, 0xnn, 0xF7
(where NN is the preset number in hex)
The response from the Rainmaker module will be a sysex stream which is in the form of an upload preset
command (see below), so that it can be replayed back to a module to upload the preset.
To
download
all 128 presets at once:
0xF0, 0x00, 0x02, 0x14, 0x02, 0xF7
There will be a series of 128 responses as when downloading a single preset.
To
upload
a single preset (from the computer to the Rainmaker module):
0xF0, 0x00, 0x02, 0x14, 0x00, 0xnn, 0xDD ... 0xCC 0xF7
where 0xDD ... are the data bytes containing the preset parameter values.

Cmb : Fbk
This point is the output of tap number 64 of the comb resonator delay line that is being fed
back to the delay input. This level is controlled by the COMB FEEDBACK amount.
◊
Cmb : ouT
This point is the output of tap number 64 of the comb resonator delay line, and forms the
output of the comb, which is then sent either to the rhythm delay input, or directly to the module output,
depending on the current module configuration. This level is controlled by the CMB GAIN (the number on
the right of the top line of the display).

sAve
This edit page allows the current module parameters and front panel knob positions to be stored in a
non-volatile memory (i.e. the memory is retained even when the power is turned off). When the SAVE button
is first pressed, the rotary encoder can be used to select which of the 128 different memory slots will be
written to. Keep in mind that whatever was previously stored in this memory slot will be over-written. The
preset number and preset name are displayed on the second line of the display. Note that the preset name
will initially be that of the last preset that was loaded (preset #1 is always loaded on power up). If you want
to change the preset name, press the SAVE button once more. Now, the rotary encoder will change the first
character of the preset name. Scroll through the list until you reach the symbol that you wish to use. Then,
press the SAVE button again. The rotary encoder will then change the second character, and so on. The preset
name can have up to 10 characters. When you have entered the desired name, and are ready to save the
preset, PUSH on the rotary encoder (ENC). The display will indicate a successful save operation by displaying an
exuberant “Saved!” message.
●
LOAD
This edit page allows the contents of one of the preset memory slots to be loaded. This will overwrite
the current module parameters with the stored values. It will also load in temporary values for the front
panel knobs (i.e. the potentiometers with knobs, but not the attenuators). These temporary values will hold
their level until the associated knob is moved by a certain amount from its current position. This means that
right after loading a preset the visual appearance of the knob’s position may not match its actual value. The
advantage is that knob positions can be stored in the preset, so for example if you had found a sweet spot
with the pitch shift knob or the comb feedback level, this could be immortalized in a preset. Turn the rotary
encoder to select which of the 128 presets you wish to load. The name of the preset will change along with
the preset number, to match the name that was stored with the preset. To actually load the preset memory
contents once you have scrolled to the desired preset number, PUSH on the rotary encoder (ENC). The display
will indicate a successful load operation by displaying the “Loaded!” message. If the LOAD button is held down
when the rotary encoder is pushed, just the parameters of the active effect (in the preset) will be loaded. This
means, for example, if you saved a preset with the COMB effect turned off, then its parameters would not be
loaded, and the previous parameter values would remain. This is useful when you want to combine the delay
parameters from one preset with the comb parameters of another.

Dly : in
This point is the input to the rhythm delay line memory, and is also the output of the mixer that
combines the delay input with the delay feedback.
◊
Dly : Fbk
This point is the tap off of the rhythm delay line memory which is being fed back to the delay
input. This level is controlled by the DELAY FEEDBACK amount.
◊
Dly : ouT
This point is the sum of all 16 of the rhythm delay taps, and forms the output of the rhythm
delay, which is then sent either to the comb resonator input, or directly to the module output, depending
on the current module configuration. This level is controlled by the DLY GAIN (the number on the left of the
top line of the display).

Cmb : in
This point is the input to the comb resonator delay line, and is also the output of the mixer that
combines the comb input with the comb feedback.
