Introduction

This instrument is built with all the familiar controls of a standard MIDI controller, instrument, or mixer. The
Ohm64 features assignable LED backlighting, custom designed rubber buttons, and high quality sliders and
knobs. The control layout was inspired by some of the most innovative and popular audio software programs
that have revolutionized the way music is created and performed. Ohm64 users will find it to be highly
intuitive and adaptable to a variety of music and video software and makes an ideal companion for hardware
such as analog synthesizers, video mixers, DJ software, lighting equipment, and other musical instruments.

Controls and Connections

While any of the controls on the Ohm64 can be used for a wide range of functionality, here are some basic
terms and uses for the controls.

Programmable Clip Bank – The Clip Bank sends out data for activating files, triggering loops,

1.
sequences, or files. The programmable buttons on the Clip Bank can be assigned to MIDI notes or
Continuous Controllers (CCs).
Programmable Sliders – These programmable vertical sliders can be used to adjust effects, mapped to

2.
pitch and volume, or used to manipulate data. The sliders can be programmed to send CC or Pitch
Bend messages.
Programmable Triggers – These programmable buttons can be used to activate effects or mute

3.
channels. The buttons can be assigned to MIDI notes or CCs.
Programmable Knobs – These programmable knobs can be used to adjust effects, EQ settings, and

4.
control playback. The knobs can be programmed to send CC or Pitch Bend messages.
Programmable Function Buttons – These programmable buttons can be used to activate various

5.
functions within the software such as: switching between channels or banks, selecting tracks, or used
to cue, play, pause, and rewind your media. The buttons can be assigned to MIDI notes, program
changes, or CCs.
Programmable Transform Buttons – These programmable buttons can be used to transform, mix,

6.
switch, or fade between channels. The buttons can be assigned to MIDI notes, program changes, or
CCs.
Programmable Crossfader – Use the crossfader to control the crossfade, mix, or transition between

7.
channels. The crossfader can be programmed to send increasing values to the left or to the right.
Programmable Tap Button – This programmable button is designed for tapping the BPM. This button

8.
can be assigned to MIDI notes, program changes, or CC’s.

MIDI IN – The MIDI Input port provides a standard 5 PIN MIDI jack for connecting other MIDI

1.
devices to the Ohm64. MIDI input data is then routed over USB to the host computer, and is available
to your software on the second port named “Ohm64 External” (on Windows XP, “USB Audio
Device[2]”)
MIDI OUT - The MIDI Output port provides a standard 5 PIN MIDI jack for outputting MIDI from

2.
your computer, over the USB cable, and to the MIDI jack. The Ohm64 will also send its data out the
MIDI jack. This MIDI Output can be accessed on your computer via the port named “Ohm64
External” (on Windows XP, “USB Audio Device[2]”)
USB – USB Port for powering the Ohm64 and sending MIDI message to and from the instrument.3.

Connecting

To make the Ohm64 controller compatible with industry standard sound and video equipment, the controller
comes equipped with both a USB and MIDI out connection. The USB is designed to connect directly to a
computer and the MIDI out can be used to connect to a MIDI interface, PC soundcard, external soundcard,
or any of the hundreds of MIDI processors and synthesizers using a standard MIDI cable. The Ohm64 is
completely USB powered and does not require an external power supply.

For Direct USB Connectivity

The Ohm64 is class-complaint and does not require drivers when using the USB connectivity.

Connect the USB cable from the computer to the USB port on the Ohm64.1.
When the logo on the Ohm64 is illuminated, the device is powered.2.

For MIDI Connectivity

Using a standard MIDI cable, connect the Ohm64 MIDI in and out to the MIDI in and out of your
sound-card or other MIDI interface. The Ohm64 must be plugged into a USB host and have MIDI software
running (even if it's something basic like MIDI Monitor (http://www.snoize.com) or MIDI OX
(http://www.midiox.com) running. This is a by-product of USB-powered class-compliant devices with no
external power source. However, once you have the Ohm64 connected to a computer and some simple
MIDI application running, you can send the Ohm's MIDI out the MIDI output jack.

Looking at the back of the Ohm64, the MIDI OUT is the input jack on the right located next to the USB
port, and the MIDI IN is the jack on the left.

Troubleshooting

Make sure your USB cable is properly connected. If you are using a USB hub, try connecting the Ohm64
USB cable directly to your computer. The lights should come on once the Ohm64 is connected.

If you are using a Macintosh Computer running OSX, make sure you have Ohm64 selected as your device in
the Audio MIDI setup. To access Audio MIDI go to Applications>Utilities>Audio MIDI Setup.

Check to make sure your software is configured to use the Ohm64. Open your application’s preferences to

verify that the software is configured to receive the MIDI messages from the Ohm64 controller.

Note: In this specification, all numbers are hexadecimal unless parenthesized or oth

Windows XP will show the port names as “USB Audio Device” and “USB Audio Device[2]”, though the
“New Hardware Found” popup will show the device as “Ohm64”.

Windows 7 will show your controller as Ohm64 and will automatically recognize the device.

If you are still having problems, confirm that you are receiving MIDI data using MidiMonitor (for OS X) at
http://www.snoize.com/MIDIMonitor/ or MIDIOX (for Windows) http://www.midiox.com.

Ohm64 Sysex

SYSTEM EXCLUSIVE COMMAND BYTES

The System Exclusive message includes the official MIDI Manufacturer ID for Livid, a Product number, and
the Command number. A "wild card" Product number allows the same commands to be shared across
multiple Livid products. These messages can be almost any number of bytes from 7 to (183) bytes.

erwise noted, in which

case they are decimal.

F0 00 01 61 02 NN ... F7

The Product number is 02 for the Ohm64, and the Command numbers, NN, are described below.

COMMAND SUMMARY

00 : individual button map (not supported) *
01 : individual control map (not supported) *
02 : Save User Settings
03 : read presets (ignored) *
04 : Set all LED indicators
05 : Recall User Settings
06 : Factory Reset
07 : Request, multiple subtypes:

07.04 : Request all LED indicators

07.06 : Request Control Surface Snapshot

07.08 : Request MIDI Settings (Local Control, etc.)

07.09 : Request Single MIDI Input mapping

07.0A : Request Analog mapping

07.0B : Request Button mapping

07.0C : Request MIDI Basic Channel

07.0D : Request MIDI Output Merge setting

07.0F : Request crossfader Flip setting
08 : MIDI Settings Response
09 : Map Single LED Indicator
0A : Map Analog Inputs
0B : Map Buttons
0C : Set MIDI Basic Channel
0D : Set MIDI Output Merge
0E : Erase entire MIDI Input Map
0F : Set crossfader Flip
7E : NAK Negative Acknowledge
7F : ACK Positive Acknowledge

Commands 0, 1, and 3 are Ohm "classic" System Exclusive commands. Even though the MIDI
Manufacturer ID is different, and the command structure is different as well, these skipped command
numbers pay tribute to what came before.

COMMAND DETAILS

02 : Save User Settings

F0 00 01 61 02 02 F7
All User Settings which can be remembered will be stored in Flash and automatically restored whenever the
Ohm64 is powered up. The Ohm64 responds with ACK when finished processing this command.

04 : Set all LED indicators

F0 00 01 61 02 04 LL HH LL HH LL HH LL HH LL HH LL HH F7
All (75) LED indicators can be set on or off with this command. There are (12) bytes, or 6 pairs of LL HH.
Values must be 7F or less. The first LL HH pair represents column 1, with each subsequent LL HH pair
representing the next column. Within each pair, LL represents the first 7 rows, and HH represents the
remaining 6 rows. There are (14) bits total for rows, but bit (11) is unavailable and reserved for future use. A
1 bit turns the LED off, a 0 bit turns it on.

The LED columns and rows do not conveniently match up with the physical layout of the Button columns
and rows. Using codes as C.R to specify column and row, the LED codes are as follows (all codes are
decimal in this table, and all columns and rows are numbered starting at 1 - the first line is the first Button
column from first to last row, etc.):
