- THE PROGRAM
- ------------------------------------------------------------------------------
-
- Introduction
-
- HD Frequency is a powerful program that allows you to create tunes based on
- a fourtrack HD-sequencer. This means that you can create long long tunes, if
- you have enough space on your hard disk left.
-
-
- Remember that this is only a cut down version of the original package, so
- MOST features are disabled:
-
- Limitations on this demo version:
-
- - Cut function disabled
- - Echo function disabled
- - Dalex function disabled
- - Phase function disabled
- - Fade Up function disabled
- - Fade down function disabled
- - Volume function disabled
- - Record length is limited to about 1 MB
- - The Sequencer is limited to 4 entries
-
- You can purchase a complete version sending a fee of $30 US or 50 DM to
- (Cash, euro cheque, postal orders ......)

- ------------------------------------------------------------------------------
- SHORT OVERVIEW OF ALL FUNCTIONS
- ------------------------------------------------------------------------------
-
- ------------------------------------------------------------------------------
- RECORD
- ------------------------------------------------------------------------------
-
-
- In this demo version the sampling rate is limited to 22 kHz. The original
- version manages sampling rates from 32 kHz on standard a500 upto over 60 kHz
- on a standard a1200.
- First choose a name for your sample, then the sample rate.
- Now press the record button. Now the VU meter shows the signal coming
- through the sampler. Now you can watch the input on the VU meter to get the
- best record level. You have the best input level if you have nearly no
- black peaks above the VU meter in the overpeak boxes.
- Now press the right mouse button to record the sample on hd.
- If your hd is to slow for a special sampling rate the program will let you
- know.
- Press the left mouse button to stop sampling.
- The sample is saved as a standard iff8SVX Sample.
-
- ------------------------------------------------------------------------------
- REPLAY
- ------------------------------------------------------------------------------
-
- Samples are shown in the big sample area on the bottom of the screen.
- If you want to replay a recorded sample. You can use the play button.
- The sample will now be replayed by DMA. You can also cue forward or backward
- while the sample is being played (ffwd. and rwed. buttons).
- To stop playing the sample press the stop button.
-
- ------------------------------------------------------------------------------
- HQ-REPLAY
- ------------------------------------------------------------------------------
-
- This is another method of replaying a sample. This routine replays a sample
- using cpu routines, dma is not used, therefore sampling rates upto 65 kHz can
- be handled by this routine. The quality of this routine is much better than
- any other dma routine.
-
- ------------------------------------------------------------------------------
- EDITING SAMPLES
- ------------------------------------------------------------------------------
-
- If a sample has been loaded you can edit it on the sample screen.
-
- MARK
-
- You can mark a part of the sample by pressing the left mouse button on the
- sample screen and releasing it somewhere else on the sample screen.
-
- ZOOM
-
- You can zoom into the sample by pressing RANGE if a mark has been picked before.
- You can move around in the zoomed range by pressing the <,> buttons on the
- very bottom of the screen.
-
- SHOW ALL
-
- Show all displays the whole sample if a sample has been ranged once
- before.
-
- FADE UP
-
- If you have marked a sample and you press FADE IN the sample will be faded
- from the beginning of the sample until the first point of the marked range.
-
- FADE DOWN
-
- If you have marked a sample and you press FADE OUT, the sample will be faded
- from the last point if the marked range until the end of the sample.
-
- CUT
-
- A marked range will be cut away from the sample
-
- VOLUME
-
- The sample will change the volume to the selected value.
-
- ECHO
-
- The Sample will be echoed to the selected value
-
- DALEX, PHASER
-
- These commands have both two parameters: The first parameter is located
- below the Dalex field. This is the length of the effect. The second
- parameter is below the phase button, this is the amplitude of the effect.
- To start the effect press one of the buttons.
-
- ------------------------------------------------------------------------------
- SEQUENCER (PLAYLIST)
- ------------------------------------------------------------------------------
-
- This sequencer allows you to create a four track tune.
- New items of the playlist have to be selected by using the NEW command,
- now you can select any iff 8svx sample.
- You can now change the parameters of the selected samples.
- Select a sample in the viewlist display. Now you are able to change the tine
- when a sample should be started being played and you can change the
- replaychannel for the sample.
- The Start time allows you to skip some samples when starting the
- routine.
-
- Of cource you can LOAD and SAVE a playlist from the project menu.
-
- ------------------------------------------------------------------------------
- 4 Track Replay
- ------------------------------------------------------------------------------
- This option allows you to replay the playlist you edited once
- before in the playlist editor.
-
- On Normal and Extended memory version the 4 channels are replayed
- using DMA access, this means that each channel is limited to max.
- 30876 Hz.
- The 68020+ Turbo Version uses a very complex 4Track CPU replay
- routine that manages replaying 4 channels at the same time.
- On A1200 you can replay 3 channels with 31 kHz or 1 channel with
- 44 kHz.
- On faster processors (=>68030 25 MHz) you can replay more
- channels with higher sampling rates. So it all depends on your
- CPU....
- If you choose to many channels or to high sampling rates on a too
- slow processor the machine might crash because of some interrupt
- overrides, in this case press the left mouse button to exit.
- ( At the moment I have no Idea how to detect this interrupt crash
- automatically...)
-
- While pressing the right mouse button during the 4 track replay
- you can skip some time (ffwd.).
- Pressing the TAB button at the moment you start the 4track, will
- blank the screen and disable most interrupts and DMA channels to
- improve the replay quality (68020+ version only).
-
- The left mouse button escapes from the routine.

- TECHNICALS
- ------------------------------------------------------------------------------
- This programm written on A1200 with 2 MB Chip, 4 MB Fast & 68882 25 MHZ &
- 120 MB Connor HD using EPU (RDCN V3.0) stakker.
- Created using ASMOne V1.01 & GadToolsbox v2.0
-
- Tested on:
-
- A500 KS 2.04 1 MB Chip 2 MB Fast, Multi-E. 2.2 85 MB Quantum ELS (ok)
- A4000/040 120 MB HD, V 37.129 tested (failed) .....
- This version now should work (hopefully), I had no chance to test it again..
-
- The Record and Replay routines take completely over the machine to get
- the best quality, so don't care about enforcer hits..
-
- These routines are using some interrupt hacks in supervisor mode, but it is
- not possible to code this part of the program in a more accurate way......
- (68000 only, turbo version freed from most hacks, because of a
- faster processor they are no longer needed).
