  • New embedded file formats for Pattern Sets, Sound Sets and Patterns. All G-Stomper files that contain references to audio samples do now embed the samples by default.
    This means you can share your patterns, pattern sets or sound sets with other users, even if they don’t have the used samples.
    This also means, once you’ve saved your G-Stomper files, you can move your userssamples whereever you’re up to (e.g. to the additional sd card), since the new embedded files will work without having the samples at their orignial location.
    If you prefer the old linked file format (which is slightly faster and also of smaller file size) you can switch the default file format to ‘linked’ in the G-Stomper Setup (see Setup / GEN / Default File format).
    The embedded file types all end with a ‘e’ in the file extension (e.g. Pattern = .gspe).
    Which files are embedded types and which are in the old style is indicated in the G-Stomper filebrowser by an ‘E’ on the file icon.

G-Stomper Studio 4.0 Release Notes:
  • New redesigned Graphical User Interface
    Complete new graphical design.
    Zillions of UI optimizations and bug fixes.
  • New overall file handling
    All File Dialogs have been replaced by a new File Browser, which allows you to organize all your user files in folder structures.
  • New User Sample integration
    Usersamples don’t need to be imported anymore, you can load every supported sample directly from the file system.
  • New SoundSet implementation
    You can now choose, what exactly you want to have saved with a soundset (Samples, Sampler Presets, VA-Beast Presets, FX1-3, Master).
  • New custom initial Pattern
    Save you own init pattern to be used in every case when a new initial pattern is created.
    Simply save your desired init pattern with the name ‘-init-’.
  • New optimized Export Process + Post Processing
    Generally the Export Process has been re-organized.
    Furthermore you get a new ‘Post Processing’ option in the Export Format Dialog, where you can choose Normalize the exported audio to -0dB (max volume).
  • New Sampler Note Grid Edit mode
    The Sampler Note Grid follows now the same logic as the Poly Grid. You can select particular Notes and note-shift or invert them.
  • Optimization in the Mixer logic
    The mixer channel volumes have been separated from the Sampler-/Synth internal Levels.
    So if you now automate the Level on a Sampler Track, you can still change its overall volume using the mixer channel.
    Furthermore the mixer channels got new internal amplifier modules, so that the audible result is exactly the same for Sampler and VA-Beast Tracks.
    Logically, the Sampler-/Synth internal Level is applied on each Voice separately at the very first moment when the sound is generated
    while the Mixer Channel Volume is applied to Sampler-/Synth internal Mixdown right before it gets routed to the FX chain.
  • New Mixer Volume Link Mode (Mixer view)
    We all know this situation when you want to make a particular track louder, but it is at max volume already.
    The only ‘proper’ way to achieve this is to lower all other channel volumes, which usually results in messing the mix up.
    Not any longer… , you can now link the mixer channel volumes to raise or lower all channels at once while keeping the relation of volumes between the channels (long press the ‘VOL’ button to enable/disable).
    When enabled, you can move any Volume Fader you want and all others follow while keeping the mix intact.
    Try it, you’ll definitely love that feature.
  • Improved Roll feature (main Drum Machine)
    You can now enable the Roll feature to be ‘Accent Aware’ (long press the ‘ROLL’ button to enable/disable).
    When enabled, the Roll uses the regular Accent amount to adjust the Loudness of the particular Roll Triggers.
    The first Roll trigger is at max volume (accentuated) while the last Roll trigger is at the min (most reduced) volume.
    All Roll triggers in between (in case of Roll 3x/4x) are calculated to transit smoothly from max to min accentuation.
    The Accent amount can be set as usual with the Accent Fader (in accent mode on the main Drum Machine).
  • Improved Fill-in algorithm (main Drum Machine)
    The Fill-in feature manipulates now Triggers and Accents (accents are only audible if an accent amount is set), while keeping the groove intact (e.g. it never places 2 accents in sequence).
    This makes the generated Fill-ins to sound much more natural, be sure to give it a try.
    The Accent amount can be set as usual with the Accent Fader (in accent mode on the main Drum Machine).
  • Full MIDI support for the VA-Beast Synth
    Check out the MIDI Documentation for further details.
  • Updated Documentation

Very special thanks to:
JYNXY for creating 3 brilliant tracks for the Promo Videos

  • New Buttons to turn the Fine Tune Mode ON/OFF
    (FX Edit, Master Edit, Mixer)
  • New Step Edit Auto-Init Steps Mode (long press Step Edit = ON/OFF)
    Since the fine tune got its own buttons in this release, the step edit buttons got the long click freed for a new useful feature, the Step Edit Auto-Init Steps Mode.
    Simply long click the Step Edit Buttons to turn it ON/OFF.What does the Auto-Init Steps Mode:
    In Step Edit – Normal Mode, if you create a single Automation event (set a Parameter value at a particular Step), then the Parameter gets set at this Step and it keeps its value until some later Step sets a new value. The Parameter actually keeps the value, because there’s no other Event in the Sequence, which sets another value.
    Depending on what you want to achieve, this behaviour might be essential, e.g. if you want to set Key Steps for the Auto-Complete Parameter Automation feature.In Step Edit – Normal Mode (if Auto-Init Steps is OFF), if you create a single Automation event (set a Parameter value at a particular Step), then the Parameter gets set at this Step and it keeps its value until some later Step sets a new value. The Parameter actually keeps the value, because there’s no other Event in the Sequence, which sets another value.
    Depending on what you want to achieve, this behaviour might be essential, e.g. if you want to set Key Steps for the Auto-Complete Parameter Automation feature.In other situations it might be better to initialize all Steps with the base value of a particular Parameter first, e.g. if you want to keep a Parameter value over the complete Pattern length and you only want to change it on a particular Step.
    In previous versions, the only way to achieve this was to explicitly initialize the Automation for a particular Parameter.With the latest version, you don’t have manually initialize anymore.
    With Auto-Init Steps Mode turned ON, if you create a single Automation event (set a Parameter value at a particular Step), then the Automation Sequence of the Parameter gets automatically initialized before the Step values gets set.

    1. Start with a fresh Pattern
    2. Select Track T01
    3. Set the Volume fader to 100
    4. Short click the Step Edit Button to turn the Step Edit Mode ON
    5. Then long click the Step Edit button to turn the Auto-Init Steps Mode ON as well
    6. Select Step 09 using the Step Buttons
    7. On Step 09, set the Volume fader to 0(zero).
    8. Now short click the Step Edit Button to turn the Step Edit Mode OFF
    9. Press Play and watch the Volume fader

  • Active Track Labels on all related screens
    New active labels which indicate if a particular track is open or closed
  • Pattern Name Labels for all Pattern Slots on the Pattern Set
  • Dynamic colorization for multi functional faders
    When switching the FX parameters from p1+2 to p3+4 for example, then the fader bars get colorized depending on their function (1st function = blue, 2nd function = red).
    If p1+2 is activ, then you control the blue bars + the fader thumb has a blue color mark
    If p3+4 is active, then you control the red bars + the fader thumb has a red color mark
    As a matter of course, the X-Y pads got the same behavior. 1st function controls the blue cross, 2nd function controls the red cross.
  • Standardized Label notation
    All Labels have been changed to normal (non-italic) uppercase letters.
  • Overall 20-30% better UI performance
    The new User Interface uses less memory as well as less cpu, so you get 20-30% more head room for audio processing.
  • Many UI bugs fixed

Very special thanks to Jan for his reports.

There are 2 main ways to use the new Rhythm Arpeggio:
(In Any way the sequencer has to be running… so press play first)

The direct fader access:
When you just touch the new fader at the right side of the steps, the Rhythm Arp acts instantly on the currently selected track.
Move the fader to change the tempo/time signature of the arp, or just touch and release the fader on different positions to create different variations.

The new Rhythm Arp Track Pad Mode:
When you switch the Trackpad mode to ‘Rhythm Arp’, then you can use the Rhythm Arp on multiple tracks at once.

  •  Right beside the Track Pads (T1-Txx) click on the Track Pad Mode button (labeled ‘Play Menu’ by default), then choose ‘Rhythm Arp/Select’.
  • Press and hold one or more of the Tx buttons (this triggers the samples continuously)

Note: When you double click a Tx button in the Rhythm Arp Mode, the double clicked track gets selected (turns green). This is very helpful if you want to tweak the sound while using the Rhythm Arp Track Pad Mode.

Furthermore you can record while you play with the Rhythm Arp (in both modes). Just hit record while the sequencer is running and use the Rhythm Arp.

  • Full Motion Sequencing support for Faders
  • VA-Beast Poly Grid (Polyphonic Step Sequencer with up to 12 tracks)

    You can map up to 13 different midi channels, one 12 to the different synthesizer tracks, and one to a merge of all sampler tracks.
    The sampler/drum tracks are mapped in an non-tonal way, all tracks (T1-24) are mapped to the noteNo 48-71:C3-A#4.
    Support for: Midi Clock, Start, Stop, Continue, NoteOn/Off, Velocity, ModWheel and PitchBend.

Most important changes (audio core):

  • VA-Beast Synthesizer Core
  • All Filters have been rebuilt from scratch
  • Many performance improvements and bugfixes in the Effects
  • Proper Resampling Algorithm in the sample loader, playback and audio exporter
  • The Master/Sum EFX provides now all Effect Types (like in the efx section)
  • The engine runs now in native samplerate, e.g. 48kHz on Nexus7 devices.
  • Major performance improvements in the audio core
  • Variable Sample Rate (settings dialog: Audio)

Most important changes (Sequencer):

  • Motion Sequencing support for the BPM/Tempo (disabled by default: can be enabled in the settings dialog)
  • New Roll feature for the samplers (known from many Grooveboxes) to send 2 or 4 triggers in a row for a single step. This allows drum rolls with a time signature up to 1/256

Most important changes (GUI):

  • The automation of the EFX chain switch is now bound to the efx automation (no longer to pattern related). It can be cleared and initialized in the EFX view like the other EFX params.
  • New fader and button tooltips (replacing the previous display values)
  • New Efx Chain switch in the EFX section
  • New State ‘VT1-12′ on EFX Edit, Master Edit and Mixer to switch to the new Synthesizer Tracks
  • The switches for ‘T1-12′, ‘T13-24′, ‘VT1-12′ are now independent on most screens. The only remaining views where these switches are synchronized is mainscreen and the sampler note grid.
  • New Mod Menu on Mixer View
  • New Efx Edit + Efx Send switch on all Sequencer Views as well as on Drum Pads
  • New Efx Edit switch on the Mixer view
  • New Song Mode Controls Layout
  • New (smaller) size of the top navigation bar
