C15 Studio Package - Manual Addendum
Introduction
In the development of the C15 we first focused on human control and pla abilit . We designed
a self-contained instrument "for those who love to pla ke s".
The implementation of a MIDI interface is now widening up the spectrum of applications for
the C15 - especiall in the studio environment.
The second extension that is included in this soware release is an internal digital recorder. It
automaticall stores the audio output signal of the last hours. Selected segments of the audio
can be downloaded in a lossless digital format. It also allows to restore the s nth engine's
state at an point in time within the recorded audio.
The MIDI Implementation of the C15
With the Studio Package, the C15 can receive and send MIDI messages. Received MIDI
messages can control the C15 and aect the sound, similar to pla ing the instrument itself.
When pla ing on the C15, MIDI messages can be sent, reflecting the performance. Note that
received MIDI messages will never be sent, so there is no "MIDI Thru" or loopback
functionalit .
Receive and Send options include a Channel (Omni, 1 ... 16) specifier, filtering events
accordingl . When a Split Sound is loaded, a secondar (Split) Channel can be used in order to
separate both Parts from each other.
As classical MIDI operates on 7 bit resolution (128 steps), there is a loss in accurac (the C15
operates on much higher precision). Nevertheless, precision can be maintained b enabling
"High Res." options. When enabled, the resolution increases to 14 bit (16384 steps). Values are
then encoded as a pair of MSB (coarse) and LSB (fine) components, eectivel doubling the
amount of messages. This is still compatible with the classical resolution, as the LSB
component is optional when receiving MIDI messages.
The C15 can send and receive MIDI messages for the following events:
Note On and Note O
When enabled, the C15 will produce sounds when receiving MIDI Note messages. Likewise, the
C15 will send MIDI Note messages when pla ing on the internal ke bed, if enabled. Note On
and O velocities are supported and can optionall operate on high resolution, using an
1
additional MIDI CC (Control Change) message on Control Number 88, encoding the LSB
component.
When a Split Sound is loaded, Notes can be received and sent on both Parts, using the
secondar (Split) Channel setting.
The eight Hardware Sources
Ph sical control elements of the C15 like a pedal or the bender are called Hardware Sources.
The can be flexibl mapped to the Macro Controls, each of which can modulate up to 90
assignable parameters.
In the C15's user interface the Hardware Sources are represented b eight sliders. Their
positions can be sent and received via MIDI in the following wa :
•Pedal 1/2/3/4 can be assigned to MIDI CCs 01...31 for the MSB while CC 33...63 can work
as LSB for 14 bit resolution. CC 64...69 can be assigned in a 2-state switching mode.
•Ribbon 1/2 can be assigned to MIDI CC 01...31 for the MSB while CC 33...63 can work as
LSB for 14 bit resolution.
•The Bender can be assigned to MIDI Pitchbend or to MIDI CC 01...31 for the MSB while
CC 33...63 can work as LSB for 14 bit resolution.
•Aertouch can be assigned to MIDI Channel Pressure or to MIDI CC 01...31 for the MSB
while CC 33...63 can work as LSB for 14 bit resolution, or to one half of the range of MIDI
Pitchbend (up or down).
Note that assignments are non-exclusive, so multiple Hardware Sources can be bound to the
same received MIDI message, as well as being merged into indistinguishable MIDI messages
when sent. This ma be useful in certain scenarios, so there are no restrictions. However, it is
up to the user to find a meaningful setting, apart from the provided default setting, consisting
of distinct assignments.
When a Split Sound is loaded, Hardware Sources can be received and sent onl on the primar
Channel. The secondar (Split) Channel setting does not appl for Hardware Sources.
Preset Selection
One of the Preset Banks can be assigned to receive and send MIDI Program Changes. The
Program Change numbers are mapped to the first 128 presets of this Bank.
MIDI Program Change messages are onl received and sent according to the primar Channel
setting. The secondar (Split) Channel setting does not appl for Program Changes.

Connecting the C15 to a USB Device
The C15 has a T pe A connector for USB, and its embedded computer s stem works as a "USB
host" for "USB devices" connected to this port. This means that ou onl need a standard USB
cable to set up a MIDI communication with an instrument, a hardware sequencer, or a MIDI
interface that has a USB T pe B connector.
Please note: If ou connect the C15 to multiple USB devices, it will onl communicate with the
one that has been connected first.
Important:
The USB port of the C15 can onl suppl a limited current to bus-powered devices.
Devices that have a higher power consumption need to be run with their own power suppl , or
through a powered hub.
Connecting the C15 to MIDI Gear that has only 5-pole DIN Connectors
To use the classical MIDI cables and 5-pin DIN Ins and Outs a MIDI interface can be connected
as an USB device directl to the USB port of the C15. The most convenient and cost eective
solution are cables with integrated USB-MIDI interface.

Connecting the C15 to a Computer
A computer running a DAW or similar is the center of man setups. It functions as a USB host
and can onl be connected to USB devices. Since the C15 is also a USB host we provide the
"MIDI Bridge" that functions as a double-sided USB device with two T pe B connectors. One of
the ports is connected to the C15 and the second to our computer.
Our adapter will appear as "NLL-MIDI-Bridge" in the list of USB MIDI devices. The two LEDs on
top of the box show the operation of the two USB Ports. If both are lit in green color the box is
working normal. If one of the LEDs ist not green, the connection to its side is interrupted. More
information about the operation of the MIDI Bridge can be found in the "MIDI-Bridge-User-
Manual.pdf".
Besides its function for the C15 the MIDI bridge can also be used for the MIDI connection
between other USB hosts, like two computers.

MIDI Settings in the Setup
In the Setup ou find a new page for "Midi Settings". It is divided into the sections "Receive",
"Send", "Local", and "Mappings".
5
Receive
Channel:
Here ou can select the MIDI channel that is used to receive MIDI messages. With Split Sounds
it is the channel for Part I, and when "Split Channel Part II" is set to "Common" it will be used
also for Part II. If ou select "Omni", messages from all 16 MIDI channels will be applied.
"None" will block all incoming MIDI messages, except in Split mode with Part II set to its own
channel.
Split Channel (Part II):
This setting applies to Split Sounds onl . It controls the MIDI channel for Note messages
received b Part II. If ou choose "Common", it is the same channel as it is set in the "Channel"
menu. If ou select "Omni", messages from all 16 MIDI channels will be applied. "None" will
block all incoming MIDI messages for Part II.
If the channel for Part II is not set to "Common", the Split Point(s) are not applied to the
received MIDI notes. Both Parts can be pla ed over the full MIDI note range.
Enable Program Change:
When set to "O", the received MIDI Program Change messages will be ignored.
Enable Notes:
When set to "O", the received MIDI Note On/O messages will be ignored.
6
Enable Hardware Sources:
When set to "O", the eight Hardware Sources will not be controlled b MIDI Control Change,
Pitchbend or Aertouch messages.
Send
Channel:
Here ou can select the MIDI channel that is used to send MIDI messages. With Split Sounds it
is the channel for Part I, and when "Split Channel (Part II)" is set to "Common" it will be used
also for Part II. "None" will block all outgoing MIDI messages, except in Split mode with Part II
set to its own channel.
Split Channel (Part II):
This setting applies to Split Sounds onl . It controls the MIDI send channel for notes pla ed in
the ke range of Part II. If ou choose "Common", it is the same channel as it is set in the
"Channel" menu. "None" will block all outgoing MIDI messages for Part II.
Enable Program Change:
When set to "O", MIDI Program Change messages will not be sent.
Enable Notes:
When set to "O", MIDI Note On/O messages will not be sent.
Enable Hardware Sources:
When set to "O", the eight Hardware Sources will not generate MIDI Control Change,
7
Pitchbend or Channel Pressure messages.
8
Local
Enable Notes:
When set to "O" the C15's ke board is disconnected from the s nth engine but still can be
used to send MIDI note messages.
Enable Hardware Sources:
When set to "O" the eight Hardware Sources are disconnected from the s nth engine but still
can be used to send MIDI Control Change, Pitchbend or Channel Pressure messages.
(In this mode the user interface displa s, e.g. the LEDs of the ribbons, do not reflect the current
positions of the Hardware Sources. This will be improved in a future update.)
9
Mappings
These settings determine which t pes and numbers of MIDI messages are assigned to the
Hardware Sources. High Resolution options for Velocities and Hardware Sources as well as a
Bank selector for Program Changes are also provided. The Mappings appl to both MIDI Send
and MIDI Receive.
