----------------------------------------- --== Zero-X ==-- DIGITAL SOUND PROCESSING SOFTWARE for Atari ----------------------------------------- Quick reference guide - 1995, March 02, 1995 !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! ! Zero-X is NOT FreeWare/PD/SW, ! ! Zero-X is a copyrighted commercial product ! ! Zero-X Demo version is FreeWare BUT any ! ! magazine that would like to place this demo ! ! on their cover disk must contact us first ! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Limitations of the demo: ======================== Please read the zx_demo.txt file. Who has use for Zero-X ====================== Everybody who has access to a sampler/sample-player and/or a harddisk-recording system and, of course, an Atari computer. What is Zero-X? =============== Zero-X is a Swedish developed GEM-based program, for Atari ST/STE/TT/Falcon, with five main tasks: 1.Automatic find the optimum looppositions for you. 2.Basic sample edit with some automatic cut functions. 3.Drum loop functions, such as split drums, create midi file, Calculate BPM, AutodrumLoop etc 4.Convert audio files of any size. 5.Transfer samples to and from samplers/sample-players etc via Midi and SCSI. Zero-X always works with 16-bit sound, stereo and mono. 8-bit sound may be loaded but will be converted to 16-bit while loading. When transferring via the MIDI-port 12-bit sound is also handled via a real-time conversion. We have tested and approved Zero-X together with the following add on products: WINX/GEMRAM, NVDI, Warp9, Selectric, TCache, Falcon 32MHz and Falcon BlowUp. Please use all of them, especially WINX/GEMRAM and NVDI! Zero-X works on ST/STE/TT/Falcon but for most optimum performance we recommend a Falcon with TOS 4.04x and a hard drive. Zero-X requires ST High (640x400) or better/more. Zero-X does not work in any True colour mode. Zero-X looks at its best in VGA 16 colour mode on TOS 4.04x, but you will get the highest performance in ST High. -------------------------------------------------------------------- Below is a short guide through Zero-X v0.9x. Some knowledge in handling Atari computers, GEM and sample devices is required. Automatic loopsearch ==================== Zero-X has two completely automatic functions dedicated to find the most optimum loop in your sample; AutoLoop and AutoSearch. AutoLoop AutoLoop compares all positions within your marked block with your entered LoopEnd and return the best fitting LoopStart. AutoSearch If you choose AutoSearch, Zero-X compare all possible LoopStarts with all possible loop-ends and then return the best/most fitting couple (loop). AutoSearch searches only within your marked block. You may also specify minimum loop width to avoid too narrow loops. Zero-X has two functions dedicated to recalculate samples that are extra hard to loop; Gate and XFade. Gate Gate changes a fading part (your loop) in the sample into equal volume. This is very useful for e.g. bass sounds and percussion sounds that often fades out too quickly and is therefore impossible to loop (i.e. if you don't use Gate!) XFade XFade recalculates the loop, i.e. making loop-start and loop-end look more alike. This means that any eventual click sound in the loop will disappear. You have full control over what part of the loop XFade shall affect. Loop control ============ In the Loop control you have access to all loop features. Choose "Loop control" in the menu under "Edit". - Minimum loop distance; This is the place where you in percentage, of your marked block, enters how close loop-start may be loop-end. This is to force Autosearch/Autoloop not to choose a too narrow loop and to speed up the search. The larger distance the faster search but you may also miss a good loop... - XFade Minimum means to XFade as little as possible. No settings are required. - XFade User This is the user defined XFade. You may enter a value in percentage of the loop distance or you may go to "Graphical edit" and mark the distance with the mouse. Graphical edit ============= To enter the Graphical edit mode, select "Graphical edit" from the "Edit" menu. This is where you can, directly in the sample, blockmark, set the loop positions (loop start and loop end), set the size of the User defined XFade, listen to the sound/sample, zoom in and out and scroll the sample in the window. Scroll is also available from the cursor (left/right) keys. There are two different wavedisplays, one which is very quick but don't show the sample accurate in overwiew mode, and the other which is very accurate in showing the sample envelope, but is not so quick (but still very quick compared to other programs!). - Toolbar Make sure that Toolbar is selected in the settings. You can select most of the edit and play functions as well as all of the edit modes from the toolbar. If you do not understand our icons, do not panic, just whatch the help text in the upper right of the screen as you place the mouse pointer on an icon. There is a little delay before the help texts appears. There are some icons for adjusting the markers position. To speed up the movement, keep pressed as you select the appropiate icon. - Blockmark (mark a section) "Block mode" In this mode you may mark a section, i.e. blockmark, by pressing the left mouse button, move the mouse pointer to the right and then release the button. The section you have marked will be inverted. - Set the loop-positions "Loop mode" In this mode you may set the loop-positions, loop-start and loop- end, by pressing the left or the right mouse button. If not both of the loop-positions are displayed, you may alternate between them by pressing . - Set the XFade User defined position "XFade mode" In this mode you may set the distance for the User defined XFade, by pressing the left mouse button within or to the left of the loop. Two sections will then be inverted. The inverted section within the loop, is the section that will be affected by the XFade. The other inverted section (to the left of the loop) is the section that will be used by Zero-X for the XFade. - DrumSplit "DrumSplitmode" In this mode you may use the DrumSplit option to split up a BeatLoop. Start with marking your BeatLoop with LoopStart and LoopEnd. Select "DrumSplit". A grid will occur and specify the different "drums" in your BeatLoop. To listen to an individual drum, select "Play block" from the toolbar. In the pro version, you have the option to create a standard midi file out of the drum split. This together with "Send all Drums" in the TransferControl gives you the possibility to actually recreate the drum loop in you sequencer, but with the great option to change the tempo without time-streching and to replace drums or even quantize specific drums etc. If you select "Save drums", all drums will be saved and given names such as "drum1", "drum2" etc. In the pro version you will also be able to select "send all DrumSplit". - Zoom, There are several icons for zooming in and out. - Playback a sample/sound There are icons in the toolbar for all kinds of playback. The sound quality on a Falcon is always 16-bit by using the build in 16-bit D/AC. The closest sample rate available will be chosen. If you are using a STE there will be a short delay before you can actually hear the sound. The sound quality is 8-bit by using the build in STE D/AC. The closest sample rate available will be chosen. If you are using an ST there will be no sound. We are working on an ST sound driver. If your sample is being looped (loop = on), you can abort the sample playback by selecting the STOP icon in the toolbar. Convert Audio-files =================== In the demo version you may only convert to .AVR. Audio files of any size may be converted as long as you have enough space left on you target drive. Select "Convert..." from the "Edit" menu. Select source and target file format. Choose Convert. Transfer samples ================ To enter the "Transfer control", select "Transfer" from the "Edit" menu. Zero-X is able to transfer your samples via MIDI, and SCSI. Your sample device has to support the Standard Midi Sample Dump format, SDS, or Ensoniq dump format. More formats will be available soon, such as Akai SCSI and Ensoniq SCSI etc. If you have a 12-bit sampler you should select "12-bit" in the "Transfer control" for the fastest and most secure transfer. To transfer samples via SCSI your sample device has to support SMDI (the, by Peavey invented, SCSI dump standard). More features ============= Fade Out ======== The volume in your marked section will smoothly be faded to zero, i.e. silence. Silence ======= The volume in your marked section will be set to zero, i.e. silence. Optimise ======== The sample will be volume optimised. SmartCut ======== If you have noise in the sample before and/or after the actual sound starts, or if you have several samples and want to cut out a single one. Simply block mark the sound and some noise before and or/after it and select SmartCut. Only the sound within your block marked section will be kept. Select "Noise Level" from the "Split Drum" menu specify the maximum noise level. Digital Noisegate ================= If you have any noise in the sample before the sound actually starts, Digital NoiseGate will remove it. Select "Noise Level" from the "Split Drum" menu to specify the maximum noise level. Note, Digital Noisegate always works from the start of your sample. Stereo support ============== Different functions in Zero-X works different on stereo sounds. All clipboard functions, Digital NoiseGate and SmartCut always works on both channels simultaneously. Silence, FadeOut, AutoLoop, AutoSearch, XFade, Reverse etc only works on one channel (i.e. left or right) at a time. There are icons for swapping the current channel in the toolbar. To AutoLoop or AutoSearch a stereo sound, we recommend you to run AutoLoop or AutoSearch in both channels. If neither result is good enough, XFade the channel who had the worst looppositions. -------------------------------------------------------------------- Current list of Distributors: ============================================= UK : Paul at the Digital Village German : Thomas Baumgaertner at SoundPool 07046-90215 USA : Steve Cohen at Wizztronic Scandinavia : Copson Data
