  3. Ensure your external device is configured to receive MIDI data on the correct channel.

5. Operating Instructions

5.1 Basic Playback

Once connected to your music software or MIDI device, simply press the keys to play notes. The velocity-sensitive keys will transmit different MIDI velocity values based on how hard you strike them, allowing for dynamic expression.

5.2 Using the Assignable Rotary Knob

The 360-degree rotary knob can be assigned to control various parameters within your music software, such as volume, pan, filter cutoff, or effect send levels. Refer to your software's manual for instructions on MIDI CC mapping.

• To Assign: Typically, you will enter a 'MIDI Learn' mode in your software, then turn the knob on the SMK-25 Mini to assign it to a parameter.
• To Operate: Once assigned, rotating the knob will adjust the corresponding parameter in your software.

5.3 Pitch Bend and Modulation

• Pitch Bend: Use the 'PITCH -' and 'PITCH +' buttons to momentarily bend the pitch of currently playing notes down or up.
• Modulation: Press the 'MOD' button to apply modulation effects (e.g., vibrato) to your sound. The specific effect and intensity are usually controlled within your music software.

5.4 Octave Shift

To access a wider range of notes beyond the 25 physical keys:

• Press 'OC-' to shift the keyboard down one octave.
• Press 'OC+' to shift the keyboard up one octave.
• The display will indicate the current octave setting.

5.5 Arpeggiator Function

The arpeggiator automatically plays a sequence of notes from a held chord.

• Press the 'ARP' button to activate the arpeggiator.
• Hold down multiple keys, and the arpeggiator will play them in a rhythmic pattern.
• Further controls for arpeggio type, rate, and gate time may be available by holding 'ARP' and pressing specific keys (refer to the markings above the keys for advanced functions).

5.6 Chord and Scale Performance

The 'SC/CH' button enables modes that simplify playing chords and scales.

• Press 'SC/CH' to toggle between Chord mode and Scale mode, or to activate/deactivate these features.
• In Chord mode, pressing a single key can trigger an entire chord.
• In Scale mode, the keys will automatically map to notes within a selected scale, making it easier to play harmonically correct melodies.
• Specific chord types and scales can often be selected by holding 'SC/CH' and pressing designated keys.
