Avoid placing the RX21 in locations exposed to direct sunlight or high temperatures, excessively high or low humidity, high dust concentration, or vibration. Be sure to connect the RX21 to an AC power supply that meets the power supply specifications listed on the rear of the unit. Ideally, you should use the PA-1 power supply unit supplied with th ...

SETTING UP Please read the PRECAUTIONS section of this manual before setting up your RX21. The CONNECTIONS diagram which folds out at the front of this manual shows you how to make the simple connections necessary to set up your RX21. Use the PA-1 power supply, or any similar power supply to convert the AC voltage to the voltage required to power t ...

THE INSTRUMENTS The RX21 contains nine superb percussion instrument sounds. Because they are Getting to Know the digitally recorded, they are indistinguishable from the real thing, and allow you to RX21 Instruments create totally authentic drum rhythms. The RX21 instruments can be played in real-time (without programming patterns or songs) by tappi ...

When you record a pattern, pressing the ACCENT key to add an accent to a beat (no need to press an instrument key at the same time) will affect ALL instruments sounding on that beat, according to their individual accent levels. For instruments which are not to be accented, simply set their accent level to zero. The accent level for each instrument ...

PATTERN OPERATIONS Pattern Selection With the RX21, a "pattern" denotes a one bar (one measure) drum sequence, which repeats when you play it back. The RX21 is capable of storing a total of 100 different patterns in its internal pattern memory. Pattern memories 56 through 99 contain 44 preset patterns that provide a variety of exciting an ...

First, select the pattern number you wish to program (numbers 00 through 55 only: patterns 56 through 99 are permanent preset patterns and cannot be re-programmed, although you can edit the preset patterns to produce new patterns, as we’ll explain in the PATTERN COPY SECTION later in this chapter). Also, ensure (by playing back if necessary) that ...

4. Press BEAT a third time, to return the RX21 to the real time write mode. You are now ready to program your pattern. Tap the red START button, and you’ll hear the “click track” rhythm accents. If, by mistake, you have selected a preset, there will be no click track. Instead, the LCD will show “PRESET PTN AREA!”, then revert to the “SE ...

For this initial explanation, we’ll assume that you’ve selected a pattern number that is empty of data. You can now set the length and quantize rate of your pattern. Press the BEAT button. If, by mistake, you have selected a pre-programmed pattern, the LCD will show the error message "PRESET PTN AREA!" then revert to the "SELECT ...

Here’s a simple example of a rhythm pattern programmed in the Step Write Mode, using a quantize rate of 1/16 (this pattern is the same as the one you entered in the real time mode). It’s shown here in regular music notation, and underneath the part of each instrument is shown in the form of a Dot Display. You can call up a Dot Display on the RX ...

You can now playback your pattern in the usual way, adjusting the tempo as desired. Quantize Basically, quantize determines the smallest note-increments which can be pro- grammed. The available qua ...

NOTE: The quantize value is set ONLY when a clear pattern is called and is being set for programming, as described in the REAL TIME PATTERN PRO- GRAMMING and STEP WRITE PATTERN PROGRAMMING sections. To make step write programming of patterns easier and more rapid, the RX21 features The Step Write Dot a Dot Display which gives a visual indication of ...
-
Yamaha RX21 - page 21
The length of the Dot Display depends on two things: the length of the pattern, and the quantize rate. For example, in a 3/4 time pattern with a quantize rate of 1/12, the empty pattern will be displayed thus: However, the LCD display only accommodates 16 beats, so in the case of a pattern with more beats (for example, a 4/4 time bar with a quantiz ...
-
Yamaha RX21 - page 22
You can use the Dot Display function to examine any pattern, whether programmed in real time or step write. This is a good way to learn what rhythms look like when displayed visually–you’ll find that even complex rhythms quantized at 1/32 look really simple on the Dot Display. Beat Exchange Once a pattern is programmed, you cannot re-program th ...
-
Yamaha RX21 - page 23
IMPORTANT: If you switch from a higher quantize rate to a lower one, only the notes occuring on the new beats will remain-all other notes will be cleared. For example, if you have programmed a part at a quantize rate of 1/32, the Beat Exchange function will switch the quantize rate to 1/16, and all notes which originally appeared on beats 2, 4, 6, ...

You can set the level of the RX21’s click track (rhythm guide during real time re- cording) before or during recording. Simply press the LEVEL key twice, then the BEAT key. You can now set the click track level using the -1/NO and +1/YES keys. The available click level range is 00–31. 00 turns off the click track. When setting the level, the -1 ...

SONG OPERATIONS In the RX21 the term "song" refers to a number of patterns connected together to form the complete rhythm track for a musical piece-for example, intro pattern, verse pattern, chorus pattern, fills, ending, etc. When used in a song, the individual patterns are referred to as “parts” of the song. The RX21 has a song memo ...

While in the edit mode, the delete function can be used to clear parts from a song The Delete Function program. For example, in the INSERT function described above, we inserted a new pattern into part 3. To delete this part, we simply locate part 3 using the -1/NO or +1/YES key, and press DELETE. The LCD will show "DELETE PART 003?". If w ...

Still in the editing mode, you can now use the -1/NO and +1/YES keys and locate the repeats, which are displayed just before the corresponding part (in the case of Begin Repeat signs) or just after (in the case of End Repeat signs) and once located, you can delete repeats in the same way as parts (see the DELETING RE- PEATS section). You can, if yo ...
