Re: why won’t my samples load after a power cycle?
WAV is a default audio format for Windows computers
AIFF is a default audio format for Macintosh computers.
When you load a sample into your Yamaha synthesizer you then can add parameters to it that control how the sample plays (forward once, loop, reverse), you can assign it an original key (a note when pressed will cause it to play at the original speed and pitch), you can assign a Key Range for that sample, you can assign a Velocity Range for that sample… This now becomes a KEYBANK. A keybank can be a small as 1 key or it can be a range of keys. Key Ranges can be horizonal (across the keyboard ) or vertical (velocity).
A mapping of keybanks is called a WAVEFORM
A WAVEFORM can contain up to 128 KEYBANKS. If you place a single sample on each Key across the keyboard you could map 128 samples to a single WAVEFORM… If you assign a different Velocity range to each sample you could stack the vertically 128 deep on a single key.
Some combination of horizonal and/or vertical mapping other than these extremes is usually what happens. For example, you may use a dozen sample mapped across the keyboard (horizonally) to create a FLUTE Voice… but you also may have two samples deep for velocity swapping (vertically) so when you strike a note hard you can have it swap to a chiff sound… So some combination of horizontal and vertical mapping is typical.
A WAVEFORM can be selected to sound in a VOICE - A Waveform in a VOICE is referred to as an ELEMENT. Elements a parameters that allow you to customize even further as to how the sample will sound… you can add Filters, Filter Envelopes (how the timbre changes over time), Amplitude envelopes (how loudness changes over time), Pitch Envelopes (how the tuning changes over time), Effects (each Element can be routed to one of two or both Insertion Effects), you can Note Shift it to a region of the keyboard, etc., etc., etc., etc.
Up to 4 Elements can be in a Voice in a Motif, and Motif ES; and up to 8 Elements in the Motif XS.
An element, when it is made up of samples, can be actually a multi-sample instrument sound… So you can combine multiple multi-sampled instruments in a VOICE (like the PIANO & STRINGS Voice) or you can use the Elements to construct a single instrument sound. Like the 8 Elements that make the FULL CONCERT GRAND piano in the XS.
All the work you do to your original raw .WAV or AIFF is not available in your Windows format audio file, or your Mac format audio file… Those are simply raw data - unprocessed. All the things I have described are “Motif parameters” added to your WAV or AIFF data.
The Motif Parameters remain in memory between power cycles - this is very important to recognize… it is the raw WAV or AIFF data that disappears and must be restored.
You can restore all of your work when you save in a Motif specific file format: ALL data or ALL VOICE data file formats. This will restore not only the Motif level parameters but the raw WAV and AIFF audio as well.
If you save as an ALL data file format you can, on the Motif and Motif ES, create an AUTOLOAD routine that will automatically reload/restore your system preferences, your songs, your patterns, and your samples - so all work that you do is automatically restored at each power up.
If you save on a Motif XS as an ALL data file or as an ALL VOICE file, you can have the XS select that file and automatically load the data when you power up.
If you apply any parameters to that raw WAV or AIFF format file… then you must save all that work in a MOTIF File Format (better, bigger and more complete) than the raw data file you started with… because it contains all the work you did to make that raw sample into a playable musical sound…
Hope that helps you understand what is going on… Samples disappear because they are housed in volatile, re-writeable RAM in the synthesizer.
Much the same as items you are working on in your computer that are housed in RAM (like your desktop)… it must be reloaded/restored every time you turn your computer on....
If you are old enough to remember when computers booted up to a C:\ prompt (that was instant ON)… you did not have to wait for you computer to come on - it was like a light switch. Poof! ON. You did not have to wait for it to power down Poof! OFF
Now that you have a pretty environment to work in and your STARTUP Menu can be quite extensive (virus protection, etc., etc., etc these load every time) - this is all done in RAM and is all loaded each time you power up… Same goes with volatile sample RAM in your synth… You can rewrite it but the trade-off is you must reload it.
If you create an AUTOLOAD file, it simply boots up ready to go… But yes it must load it. Autoload like your computers START UP MENU simply automates it so you don’t have to do it every time.
Make sense?
