JUNO-G Version 2.0

Synthesizer

Q.The JUNO-G has a Patch mode and a Performance mode, as well as "songs," "samples," "MIDI tracks," and "audio tracks." What are these?

A.

Patch mode and Performance mode


When you're selecting sounds in the JUNO-G and playing them from the keyboard, you can use the sound generator in either Patch mode or Performance mode. Choose the mode that's best for the way you want to play the JUNO-G.
  • Patch mode
    In this mode, you can use the keyboard to play a single sound (patch or rhythm set). The sound generator responds to MIDI data received on a single MIDI channel.
  • Performance mode
    In this mode, you can perform or record using multiple sounds (patches or rhythm sets). In addition, the sound generator responds to MIDI data received on all 16 MIDI channels.

Songs, MIDI tracks, audio tracks, and samples


Here we discuss how songs, MIDI tracks, audio tracks, and samples are related


Song
In the JUNO-G's song recorder, the performance data for an entire composition is called a "song." This performance data is recorded on MIDI tracks (MIDI channels 1-16) and audio tracks (1-4). A song also includes a tempo track and a beat track as well.
Note: A "track" is an area used to record musical performance data.

  • MIDI tracks 1-16
    Your playing on the keyboard--along with your operations of the JUNO-G's various controllers--are recorded in the song's MIDI tracks as "MIDI messages." When you play back the song, the MIDI messages recorded on the MIDI tracks are sent to the sound generator, making it produce sound. Once recorded, the MIDI tracks play the instruments in place of you.

    The recording of MIDI tracks might seem similar to how an audio recorder captures sound, but there is an important difference: an audio recorder captures the sound itself, while a MIDI recorder captures the actions (key strikes and controller movements, etc.) that produce and control the sound. MIDI recording provides several advantages over audio recording: the performance can be easily edited after recording, song tempo can be changed without affecting the pitch, and the sound quality never deteriorates.

    The MIDI tracks record the performance data of 16 MIDI channels, allowing simultaneous playback of up to 16 different sounds.

    In Performance mode, the 16 parts of the sound generator correspond to the 16 MIDI channels. In Patch mode, your keyboard playing is recorded on MIDI channel 1 and the rhythm pattern performance is recorded on MIDI channel 10 (factory setting).
  • Audio tracks 1-4
    The audio tracks in a song handle samples that are captured by audio track recording or imported from WAV/AIFF audio files. Even if you change the tempo during a song, audio tracks are time-stretched so that they will always remain in synchronization. You can also begin playing from the middle of a sample.

    The actual sample itself is not recorded on the audio track. Rather, the audio track records only a "sample event" that tells the sound generator to, for example, "play USER (or CARD) sample number 'x' at this point." This means that even if you delete the sample event from the audio track, the sample data itself will remain. Up to 256 sample events can be placed on each audio track.

    Note: An audio track can play only one sample at a time. If sample events overlap, the one that is later in the track will take priority and will sound.

  • Samples
    A JUNO-G "sample" is a digital recording of a sound created by audio track recording on the JUNO-G. (WAV/AIFF format files that you import into the JUNO-G via USB are also handled as samples.) A sample consists of the actual waveform data, along with parameters such as the start point, loop start, and loop end that tell the JUNO-G how to play the sample. The JUNO-G can hold a maximum of 9000 samples (2000 user samples and 7000 card samples).

    As with a conventional sampler, you can use the JUNO-G to play a sample as a patch (sample patch), or use samples as waveforms in a patch or rhythm set.



Additional notes for your reference

  • Tempo track
    A song's tempo track contains information about tempo changes in the song. This tempo information can be entered manually or recorded in real time.

    When you make the first recording in a new song, the current tempo setting is recorded and stored at the beginning of the tempo track. When playback starts, the song will always play at this initial tempo. If desired, you can freely change this initial tempo by editing it in the tempo track. (You can also manually adjust the tempo after playback starts; however, the tempo will revert to the setting in the tempo track when playback is stopped and restarted.)

    If you want the song to play at a constant tempo, you only need to concerned with the initial tempo at the beginning of the tempo track. If you wish, you can record tempo changes throughout the song by recording them in the tempo track in real time, or manually adding them one at a time by editing the tempo track.

  • Beat track
    The beat track specifies the time signature of each measure in the song. Use the beat track to set the initial time signature and any subsequent time signature changes thereafter. (4/4 is the default time signature.)
