Digital Sound Sample Playback and Manipulation System
-----------------------------------------------------
Version 2 Rowan McKenzie 4/5/89
(C) Copyright 1989 by Rowan McKenzie
New features in version 2:
* Source code ported to Turbo Pascal V5
* Assembler code optimised to allow SOME slower XTs to work in the
PWM speaker mode.
* Mouse control! (no more memorising single key functions)
* Keyboard mouse emulation if no mouse is available.
* Pull down menus!
* Sound files are now up to 64k long (twice the previous duration)
* Sound file reading and writing has been speeded-up by a factor of
about 5!
* Improved appearance.
* low level code has been speeded-up to allow slightly faster sample
rates.
* Pitch and timer duration are controlled from click boxes on screen.
* All major settings can be altered from a single menu box.
* Built-in brief help box.
* A mouse controlled universal cut-box specifies regions for
functions to be applied to.
* Manipulating sections of waveforms is now done via the
cut/copy/paste method. Also, it is possible to mix sounds while
pasting to combine waveforms.
* Waveform regions can be cleared.
* A zoom facility allows small details to be manipulated (remove
those annoying clicks where sounds are joined).
* Direct editing of zoomed details by drawing with the mouse.
* Monitor facility (A/D required) allows the input signal to be heard
before sampling.
* A reference pitch (concert A) is available when preparing to sample
a sound.
* No special keyboard command mode exists. The keyboard is now in a
permanent instrument mode thanks to mouse control.
Bug fixes since V1.2:
* Setting sample rate now works correctly.
* Clicking noise between sounds when key pressed or released for PWM
version has been eliminated, however autorepeat still causes slight
clicking while holding key down.
SAMPLER is still true public domain!
