C15 Studio Package - Addendum
Introduction
In the development of the C15 we first focused on human control and playability. We designed
a self-contained instrument "for those who love to play keys".
The implementation of a MIDI interface is now widening up the spectrum of applications for
the C15 - especially in the studio environment.
The second extension that is included in this soware release is an internal digital recorder. It
automatically 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 synth engine's
state at any point in time within the recorded audio.
The MIDI Implementation of the C15
Since the Studio Package update the C15 can receive and send MIDI messages. Received MIDI
messages can control the C15 and aect the sound, similar to playing the instrument itself.
When playing 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
functionality.
Receive and Send options include a Channel (Omni, 1 ... 16) specifier, filtering events
accordingly. When a Split Sound is loaded, a secondary (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 accuracy (the C15
operates on much higher precision). Nevertheless, precision can be maintained by enabling
"High Res." options. When enabled, the resolution increases to 14 bit (16384 steps). Values are
then encoded as a pair of MS (coarse) and LS (fine) components, eectively doubling the
amount of messages. This is still compatible with the classical resolution, as the LS
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 playing on the internal keybed, if enabled. Note On
and O velocities are supported and can optionally operate on high resolution, using an
additional MIDI CC (Control Change) message on Control Number 88, encoding the LS
component.
When a Split Sound is loaded, Notes can be received and sent on both Parts, using the
secondary (Split) Channel setting.

The eight Hardware ources
Physical control elements of the C15 like a pedal or the bender are called Hardware Sources.
They can be flexibly 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 by eight sliders. Their
positions can be sent and received via MIDI in the following way:
•Pedal 1/2/3/4 can be assigned to MIDI CCs 01...31 for the MS while CC 33...63 can work as
LS 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 MS while CC 33...63 can work as LS
for 14 bit resolution.
•The ender can be assigned to MIDI Pitchbend or to MIDI CC 01...31 for the MS while CC
33...63 can work as LS for 14 bit resolution.
•Aertouch can be assigned to MIDI Channel Pressure or to MIDI CC 01...31 for the MS while
CC 33...63 can work as LS 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 may 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 only on the primary
Channel. The secondary (Split) Channel setting does not apply for Hardware Sources.
Preset election
One of the Preset anks can be assigned to receive and send MIDI Program Changes. The
Program Change numbers are mapped to the first 128 presets of this ank.
MIDI Program Change messages are only received and sent according to the primary Channel
setting. The secondary (Split) Channel setting does not apply for Program Changes.

Connecting the C15 to a U B Device
The C15 has a Type A connector for US , and its embedded computer system works as a "US
host" for "US devices" connected to this port. This means that you only need a standard US
cable to set up a MIDI communication with an instrument, a hardware sequencer, or a MIDI
interface that has a US Type connector. You can connect the C15 to multiple US MIDI
devices via a US hub.
Important: The US port of the C15 can only supply a limited current to bus-powered devices.
Devices that have a higher power consumption need to be run with their own power supply, or
through a powered hub.
Connecting the C15 via 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 US device directly to the US port of the C15. The most convenient and cost eective
solution are cables with integrated US -MIDI interface.

Connecting the C15 to a Computer
A computer running a DAW or similar is the center of many setups. It functions as a US host
and can only be connected to US devices. Since the C15 is also a US host we provide the
"MIDI ridge" that functions as a double-sided US device with two Type connectors. One of
the ports is connected to the C15 and the second to your computer.
Our adapter will appear as "NLL-MIDI- ridge" in the list of US MIDI devices. The two LEDs on
top of the box show the operation of the two US 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 ridge can be found in the "MIDI- ridge-User-
Manual.pdf".
esides its function for the C15 the MIDI bridge can also be used for the MIDI connection
between other US hosts, like two computers.

MIDI ettings
In the Setup (both in the graphical UI and on the hardware) you find a new page for "Midi
Settings". It is divided into the sections "Receive", "Send", "Local", and "Mappings".
7
MIDI ettings: Receive
Channel
Here you 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 you 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.
8
plit Channel (Part II)
This setting applies to Split Sounds only. It controls the MIDI channel for Note messages
received by Part II. If you choose "Common", it is the same channel as it is set in the "Channel"
menu. If you 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. oth Parts can be played 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.
Enable Hardware ources
When set to "O", the eight Hardware Sources will not be controlled by MIDI Control Change,
Pitchbend or Aertouch messages.

MIDI ettings: end
Channel
Here you 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.
plit Channel (Part II)
This setting applies to Split Sounds only. It controls the MIDI send channel for notes played in
the key range of Part II. If you 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.
