Tips & Tricks
Quick switch between 2 different OSC pages
you can switch directly between two OSC pages using the [OSC WAVE] & MACRO CTRL encoder
[OSC WAVE] memorizes the last selected page
[MACRO CTRL] memorizes any page between 10 and 26
Sometimes an Encoder memorizes two pages - needs further investigation and description
Shorten a motif
press [MOTIF] and then display encoder [EDIT] <br> the following display page allows you to change the length & loop type of a motif
Init Sound
[SHIFT]+[SET ROUTING] intializes the H-Synth Part. <br> You don't hear anything afterwards, because alle TriggerGroups are cleared. Hold down [12/Analog Synth] while in Part Select Mode to enter the TriggerGroup Pages, then use the Page Keys to access the TriggerGroup assign Pages. Assign all Elements to TG1 for a normal H-Synth Sound.
How to use different FX Send Levels for MM Filter, LP Filter and Filterbank
Beside the H-Synth global FX1 Send accesible via [FX1-SEND] there are different FX1 Send controls for MM Filter, LP Filter and the Filterbank.
The Send for MM & LP Filter can be found in the [EG DEPTH] menu page 5&6. The Filterbank FX1 Send has a dedicated knob [FB>FX1/12].
Different FX Levels are usefull if you have multiple TriggerGroup, for example a dry LP Bass Sound, a MM Lead Sound with medium delay and a Filterbank with lots of delay.
LFOs have no effect
The the [MOD DEPTH] of the global LFOs must be > 0, because the mod depth is the master Level control for a global LFO.
The Voice/Filter LFOs only work as a mod source if their original Amount is > 0.
Example : You can only modulate TLM of OSC1 with the LP Filter LFO if the LP Filter LFO has a Mod Depth > 0
Dyn and Fix in the file system
To save the settings for dynamic (Dyn) or fixed (Fix) loading, the archive flag of the FAT file system is used. Archive flag on is equivalent to fixed loading. Dynamic loading means the archive flag is off.
Backups on Windows
There is a freeware tool called Robocopy which is included since Windows Vista. It allows to not change the file attributes like the archive flag which is important for the Spectralis.

Gilde : Glide Amount
Pitch : Pitch is the root key of the scale function. If you set the pitch to C3, the C3 of the keyboard will give you the original pitch - the keys above will react like set in the scale function and below the root in the opposite direction down.
Scale: By default, the scale is set to 12 - that means an octave has 12 halftones. Each halftone is a 1/12 octave step if set to 12. If you set the parameter to -12, each key to the right on your keyboard will have a 1/12 Octave lower pitch - so the keyboard is reversed then. (It is often fun to try a running sequencer line with one oscillator set to 12 and one to -12. Sometimes a coarse tuning together with a negative scale gives good sonic results.
But you can set the scale also to 1 - that means the next halftone will be reached if you press one octave up at the keyboard. If it is set to 0, the pitch will not be changed at all. Each note at the keyboard then has an equal pitch. You can use this feature for all oscillators independently. Its a good way for creating clusters and FX sounds - especially when the oscillators are modulating each other with FM or PM.

Routing Diagram
This is a draft version of a routing diagram of the spectralis signal path.
You may need a special svg viewer for the file like inkscape.
Adding your own samples
With the software Spectralis Importer you can import 44,1 KHz, 16 bit .wav files or Soundfont files (for multisamples) and convert them to Spectralis compatible files.
You can create Soundfont files with Viena (Win32) and Swami (Linux).
Links
- http://www.sequencer.de/syns/radikal/Spectralis.html
- Spectralis User Forum
- Viena (Soundfont editor for Win32, does not need a Soundblaster card)
- Swami (Soundfont editor for Linux)
I would like to thank the following people:
- Lichttank from the spectralis forum for contributing the routing diagram.
- Jörg Schaaf for further parameter explanations (and for creating this wonderful machine)
