The C15 also features a few global settings that are preset-independent. They are organized in the Menu and mainly define the interaction with peripherals (such as sensitivities for velocities, external pedal integration, MIDI, or connected devices via Wi-Fi). Besides, the Setup menu allows for installing updates and transferring backups.
Chapter Setup Navigation provides all information on accessing and navigating the Setup menu both on the Unit and on the User Interface. The following passages explain all provided menu items.
The Velocity Curve determines the sensitivity of the instrument for key velocities. A soft setting increases the sensitivity for low velocities, a hard setting increases the sensitivity for high velocites. With the normal setting, the sensitivity remains equal for all velocites.
The Aftertouch Curve determines the sensitivity of the instrument for Aftertouch gestures. A soft setting increases the sensitivity for low aftertouch intensities, a hard setting increases the sensitivity for high aftertouch intensities. With the normal setting, the sensitivity remains equal throughout.
The Bender Curve determines the sensitivity of the instrument for Bender gestures. A soft setting increases the sensitivity for low bending intensities, a hard setting increases the sensitivity for high bending intensities. With the normal setting, the sensitivity remains equal throughout.
As described in chapter Using Hardware Sources the integration of pedals can be done manually. External Pedals can be connected to the C15 while the device is running. In the Settings menu, the pedal’s Assignment can be selected. Those may vary depending on the pedal vendor (Roland uses Pot Tip Active
, Yamaha uses Pot Ring Active
, for example). If uncertain, which setting should apply to your external pedal, try the different options until the pedal works as intended.
When an external pedal has been connected, it needs to be calibrated. This can be achieved by slowly turning the pedal to its minimal state and after remaining there for around a second, slowly turning the pedal to its maximal state and remaining there for around a second. The calibration will be stored by the C15, so the calibration is only necessary once after a pedal has been plugged in, even after restarts of the device.
This option can be enabled in order to avoid drastical changing pitches and other emerging artifacts, being provoked by a preset change. The suppression will be realized by clearing (flushing) all delay buffers when a new preset is loaded.
Note that this feature is not fully implemented yet, as the suppression is not perfect in every case and can still produce small artifacts, depending on the preset change's circumstances. But in general, the effect is quite noticeable.
For and Sounds, different Parts can be shown on the C15’s Display and on one or multiple instances of the User Interface. This can be useful but in many cases it was confusing. Therefore the normal behaviour is that the Part selection is applied once to all UIs, corresponding to Sync Parts across UIs
being on. When the option is set off the Parts can be selected separately.
When editing a parameter, the new adjusted value will be approached within the Edit Smoothing Time, which can range between zero and 200 ms. Higher times will lead to a slower response of the sound engine. This time does not affect preset recalls or modulations (having their own, individual times).
The transition time will be effective when recalling presets, defining the smoothing time of the parameters as they approach their new values.
The tuning of the C15 can be adjusted in order to fit with acoustic instruments, spanning from 400.0 Hz up to 480.0 Hz (default: 440.0 Hz). When using default parameter values(1), pressing the A3 key will produce a tone with the exact frequency provided by this setting.
1) required default parameter values for: Transposition (no Note Shift), Pitch (at 60.00 st, incl. Key Tracking of 100.0 % and Env C at 0.0 st), Scaling (Offset for A at 0.0 ct).
As described in chapter Editing a Parameter (and Manipulating Sounds), specific parameters (and whole Sounds) can be set to their default values. The current Sound can be used for overwriting these default values by pressing Store
. In order to restore the Factory default values, press Reset
.
A complete reference to the settings of the User Interface can be found in chapter GUI Settings.
The in the Panel can detect acceleration gestures and apply them to an item in focus accordingly. With sufficient acceleration, even high resolution parameters can be completely traversed with only one or a few turns of the Encoder.
Similarly, drag gestures on the two touchstrips can be amplified by the Ribbon Relative Factor. This option is only effective, when a Ribbon is in relative mode.
As described in chapter Overviews the Flow Overview allows for a fast and easy impression on how signals of a preset are routed. However, blinking LEDs may distract the user in some cases, therefore the Flow Overview is optional.
An optional timeout setting has been added in order to prevent possible pixel deterioration in the two displays, which can occur when the C15 is running for longer periods of time without any interaction.
When the screensaver is running, any interaction will interrupt it and reset the timeout.
A complete reference to the MIDI settings can be found in chapter MIDI.
With the option Auto-Start Recorder
the user can decide if the audio recording starts automatically when the C15 is switched on, or if the user has to start it by the Button (see chapter Recorder for more details).
The Device Name of the C15 instrument can be chosen by the user. It will appear in the meta data of presets and determine the SSID of the Wi-Fi network. In order to complete the renaming process, restart the instrument afterwards.
During the booting process, the SSID will be generated according to the Device Name. A Wi-Fi network with the SSID should be available after booting. Besides the Device Name, the SSID contains a static prefix (NL-C15-
). When establishing a Wi-Fi connection, choose the network with the corresponding SSID.
The secured Wi-Fi connection has to be confirmed by a passphrase. This passphrase can be seen and changed in the System Info (effective after rebooting). The passphrase can be set manually, it can be randomly generated or set to default (88888888
).
When a Wi-Fi connection was established, the User Interface is available with the shown address, which can be typed into your browser's address bar.
The remaining free disk space is displayed in order to see, if the instrument is capable of holding more presets.
For developers, the system's current RAM consumption is indicated.
For developers, the Device Hardware ID and versions of integrated components are displayed as well.
The instrument contains its own system clock, which will be included in preset meta data in the form of timestamps. It can be adjusted as well.
If a USB stick with a new (not already installed) update file is connected to the C15, this entry will indicate this with Yes
. When restarting the C15, the update will be installed.
For developers, the number of detected Audio buffer underruns is indicated, hinting at performance issues.
If an external device is connected to the C15, a software update file can be directly uploaded. The C15 will then restart and install the update.
In the About section, the Nonlinear Labs developer team is listed.
In order to backup all banks or restore a preexisting backup, a USB stick has to be plugged in. The USB Available
indicator shows if a USB stick is currently present.
When entering the Save all Banks
option, a dialog will indicate that this process may take a while (when many banks are present) and ask for confirmation. After confirming, a backup file will be created on the USB stick.
When entering the Restore all Banks
option, a dialog will indicate that all present banks will be discarded when proceeding. After confirming, another dialog screen will provide a list of all backup files found on the USB stick. After selecting the right file, the backup process can be started by confirming.
Details on how to save or restore backups on the User Interface can be found in chapter Backups.
