- Q. I have converted some files with loops, but they sounds with clicks, Why?
-
- A. This may be for several reasons.
-
- The first and often the most important is due to the bad loop points
- choosed at the original file.
-
- The second is due to several formats use a loopfraction, for the best
- tuning of the loop points (for example PAT and INS formats); here, loop
- points are not located in a sample, they are located between samples
- (1/3, 1/5 of sample...). Since these wavesamples never have exact loop
- points, the conversion will have a lightly click. Convert try to
- aproximate the wavesample loop points at the near sample.
-
- Another reason can be due to several formats contains several loop
- points (like SMP), and Convert uses the first. Can be this point is not
- the best.

- Q. How can I use loop points stored into WAV files by Convert?
-
- A. Convert store loop points into WAV files as CUE points. You can manipulate
- loop points from programs let's you work with this CUE points (standard WAV
- specification). Some of these programs are Cool Editor (select the "Loop Range"
- CUE point), and GoldWave (select the "Loop Start" and "Loop End" CUE points).

- Q. I have several KRZ files named "name.kr1" up to "name.kr4", but Convert
- give me an error, what happens?
-
- A. Kurzweil samplers divide files larger than 1 disquette into several pieces.
- Probably, "name.kr?" is a piece of a great file. Before using Convert, you have
- to reasemble all pieces into a file. This can be done using JOIN, a utility
- supplied with Convert: JOIN name.krz will create a file called "name.krz" from
- "name.kr1", "name.kr2"...

- Q. I have several GKH files named "name1.gkh" up to "name4.gkh", but Convert
- give me an error with internal files, what happens?
-
- A. Similary to Kurzweil, Ensoniq divide large files into several disquettes.
- Each GKH file you have is a disquette, which contains for example the file
- "name.ins". All GKH files have "name.ins", but each one is a piece of the
- original file. To reassemble you must to do this:
-
- 1. Extract the contents of each GKH file individually (don't try *.GKH
- because this will override existing files with the same name) and
- rename the piece. For example: Convert name1.gkh -out
- ren name.ins name.in1
- Convert name2.gkh -out
- ren name.ins name.in2
- .....................
- 2. Use the JOIN utility: Join name.ins
- This will create a file called name.ins which can be used by Convert.

- Q. I agree with the Bidirectional to Forward Looping conversion but I want
- convert my bidirectional looped wavesample without looping, how can I do it?
-
- A. Convert has an useful way to use bidirectional looped wavesamples with
- formats which have only forward loop. This is made by increasing the wavesample
- size and this can be no desirable. Then you can use the "-b" switch, which
- maintains the original wavesample size and loop points, but lost the perfect
- loop, in order to change to forward.

- Q. I agree with the Stereo to SBK conversion but I want to convert my stereo
- wavesample to SBK in mono, how can I do it?
-
- A. Convert uses multilayering to work with stereo wavesamples. This is made
- using the left channel and the right channel as two layers with differents
- panning positions (0 and 127). This can be avoided if you specify the "-1"
- switch (the standard force mono switch).
-

- Q. How can I separate drum sounds from Drum Kits?
-
- A. Often, a Drum Kit is an instrument with many waveforms (generally
- percussion), each one assigned to one MIDI key. Convert try Drum Kits as
- standard instruments, that is, when you convert it to a format with instrument
- capabilites, it maintains the same structure. To extract individual waveforms,
- you can first convert it to a format without instrument capabilities, as WAV,
- and latter convert each waveform to an instrument (Convert *.WAV -SBK).

- Q. I have several good stereo 16 bit instruments, but once converted by Convert
- to S3I format, Scream Tracker 3 sounds bad, Why?
-
- A. Although S3I format has been designed for supporting stereo 16 bit samples,
- Scream Tracker 3 only works with 8 bit samples. Convert supports S3I at 16 bit
- and stereo like specifications stablishes for future versions of Scream Tracker
- but in order to use samples into Scream Tracker version 3, you must to add the
- "-8 -1" switches at command line to force 8 bit mono samples. Other tracker
- formats have similar problems, in each case you must use the "-8" or/and "-1"
- switches to fix them.

- Q. What the -g switch means?
-
- A. The Gravis Ultrasound Drivers are designed actually to use only the portion
- of the sample defined until the loopend point, that is, when you loop a wave,
- the sustain and the release parts use the loop range to maintain or terminate
- slowly the sound. There are PAT files around the internet (for example ProPATs)
- which have some click or some kind of noise in the last part of the wavesample
- (between the loopend and the end of the wave) not audible with the GUS. The -g
- switch (means Gravis correct) force to save only until the loopend point of
- a PAT file, avoiding this noise at end of wavesample. Use it if you find some
- kind of noise at the end of a PAT file.
