RhythmX #3 (4 minutes).
We’ll look at how to transpose a part or all parts. For example, you may be practicing a scale sequence in one key, and now want to practice in a different key. We’ll use the RhythmX#2 snappet for this.
We’ll then add a couple of “memos” to a separate track/part that show us a pattern we want to use for improvising at different points of the tune. These are visual reminders that stay in place during playback, until replaced by another memo on the same part later in the playback.
What you will learn
You will learn how to use the transpose dialogue that is part of RhythmX. Then you will learn how ato add memos. Finally you will learn how to time-displace a part.
Each of the following sections can be expanded by clicking on its heading, and collapsed by clicking on the heading again.
Transposing RhythmX content
Now load up one of the snappets that you encountered in RhythmX #2. You are going to transpose its contents
Bringing up the “Transpose” dialogue
- Click “Back” to the main toolbar
- Click “Transpose…” on the main toolbar. The dialogue appears.
- In the box next to the label “Enter number of semitones (can be -ve), type -4, followed by Enter. We are going to make the whole tune 4 semitones lower.
- The three transpose buttons at the bottom of the dialogue become enabled. (If they don’t, try typing the number again).
- Click “Transpose All”. Visualisation is turned off (e.g Any track linked to the active track is unlinked). Everything (apart from drums) are transposed. Scale shapes, chords etc, will all shift down the neck (towards the nut)
- Start playback to have a listen.
- Click on visual feedback dropdown and select “Link track to active layer”. Click any onset on the “gtr chord” track
- Start playback to have a listen and see the chords have all shifted.
- Bring up the “Transpose ” dialogue again, and this time enter +6, followed by Enter.
- Have a listen. Stop playback.
Adding memos to a part
The intention here is to present visual reminders of scale or chord shapes during playback, suitable positioned at the different parts of the music, that remain visible as long as you want. The shape could be anything, a scale, an edited scale, with notes deleted, a scale fragment.
- On the main toolbar, click “Create Track”.
- Name the track “memo track” and click “Create”
- Click “Define Part” for this track, and set it for 4/4, 8 bars, quarter notes, and click “Create part”
- Enter the toolkit, move the anchor to the 7th fret on the 4th string, click on “Scale” and scroll down to click on “Minor pentatonic”
- Switch to “Refine part” toolbar.
- Click “Memo” and click on the 4th onset of the memo track. An “H” appears at that onset, representing a memo.
- Click “Join right”. Click on the 4th onset eight times, making it a much longer duration.
- Choose “Aeolian” from “Scale”
- Click the 5th icon from the left in the icon block at the top of emuso.
- Left-drag out a rectangle starting at the 7th fret on the 4th string, and extending to the 12th fret on the 3rd string. This is a scale fragment.
- Click “Memo” and click on the 5th onset of the memo track.
- Click “Join right”. Click on the 5th onset eight times, making it a much longer duration.
- Click “Back” to the main toolbar.
- Click “Link track to active layer” and click any onset of the memo track.
- Start playback. Each memo will appear for as long as its duration lasts. Stop playback.
This is excellent for experimenting with the placement of notes within the rhythm. This can make a big difference in what the listener feels.
- If needed, switch to the Refine part toolbar.
- Click “Time displace…”
- Use the dropdown next to “Divided by” and select “1”. Combined with the “Note value” of quarter note, this means that the displacement will shift the part by some number of quarter notes. DIfferent shift amounts can be set up using these two dropdowns.
- Change the “Shift count” drop down to 2. The onsets in the part will shift by 2 quarter notes
- Click on the button “Early”. The shift, when applied, moves the onsets towards the front of the part, so their contents sound earlier in time than previously.
- Click the “Displace” button to activate the time displacement command
- Click any onset in the “grt melody” part. The shift is applied.
- (Type CTL-Z to undo the shift).
- The command remains aactive until you close the dialogue, or choose another Refine part command.
If you clicked on “wrap”, then the onsets that “fall off” the end of the part (with shift late) enter the part at the beginning. With shift early, onsets that “fall off” the beginningh of the part enter the part at the end.
The next quick start looks at a few more features of the toolkit, including pitch classes, changing the guitar or bass tuning, switching between left-handed and right-handedguitar or bass, and inventing your own chord and scale shapes.
