INSTRUMENTS / GENERATORS Transistor Bass TRIAL ONLY: Transistor Bass is available as a trial version in FL Studio and needs to be purchased separately. Transistor Bass is a subtractive synthesizer in the style of the legendary Roland TB303™ Bassline synthesizer, but also enhances the concept by offering a number of tweaks not found in the original hardware, together with a guitar distortion, FX and a modern sequencer. Plus, fast editing of your bassline sequences. Video Tutorials Click to watch the Transistor Bass video tutorials. Parameters There are 128 'Programs'. Each program consists of a Patch (the state of all synthesis controls for Transistor Bass) and a Sequence (a melody that plays when the Sequencer is activated). You can change the Program value with the Note/Key selector or when AF (Auto Follow) is on, the Program will change depending on the note sent to the plugin (C0 to G10). Independent of the Programs are 128 Sequences that can be used with any of the Programs. Sequences can be set from 1 to 16 steps. In addition you can use Piano roll slide notes and note colors. Title Bar Edit Menu - Copy/Paste Sequence or Patches (parameters), Select a UI theme or check the About Panel.

Show Panels - Configure Transistor Bass to show the following panels [Main], [Main] + [Tweaks, Distortion], [Main] + [Tweaks, Distortion] + [Delay, Reverb] or [Main] + [Tweaks, Distortion] + [Delay, Reverb] + [Sequencer]. Main Panel AF (Autofollow) - When selected and the Sequencer is also activated: The active / editable Program automatically changes with input notes. Use this to change the Program and associated Sequence on-the-fly. Deselect when you want to tweak a Program and don't want input notes from FL Studio to change it while you are working on the Program.

(Autofollow) - When selected the Sequencer is also activated: The active / editable Program automatically changes with input notes. Use this to change the Program and associated Sequence on-the-fly. Deselect when you want to tweak a Program and don't want input notes from FL Studio to change it while you are working on the Program. Program - Each program is linked to one of the 128 MIDI notes (C0 to G10). Use the selector to choose one of the 128 'Program' slots. In AF mode, each of the 128 MIDI notes will select each of the 128 Programs. Each Program can be linked to any of the 128 Patches and 128 Sequences. This means that 2 or more Programs can share the same Patch and or Sequence. Sharing is useful when you want different MIDI notes to play different Sequences, but with the same Patch (sound). When not in AF Mode, the Program won't change unless you do it via the Program selector on the interface.

Read / Write (Patch parameters Edit Buffer) - When you edit parameters or they are modified by automation, they are not stored to the current Patch immediately. More specifically, each Patch has a 'working' edit buffer . This avoids overwriting precious and carefully crafted Programs: You'll always be able to return to the original Patch settings when you mess something up by clickiong the ' Read ' button. If you are satisfied, you can permanently keep the Patch edit buffer by pressing the ' Write ' button. Read - Read Patch permanent buffer into Patch edit buffer. Write - Write Patch edit buffer to Patch permanent buffer. The button will light to indicate the change. Additionally, Patch edit buffers are stored when you save your song. When you load it again, WRITE will be lit if you didn't press it before saving.

- Accent amount. Accents momentarily increases the filter , and wave . When not using the internal sequencer, accented notes are triggered with a velocity greater than 100 Volume - Output level from the sound engine. This volume is applied BEFORE the Distortion section! Controls Panel Tweaks - These controls influence the oscillator. HP - Frequency of the high-pass filter (the original TB-303 has a fixed-frequency highpass). Use this to adjust the output to be more or less 'bassy'. Min Envelope Decay - Minimum Filter Envelope decay time. This has a strong influence on accented notes, because the accent circuit uses this relies on this parameter. This is probably THE parameter that defines why one TB-303 emulation sounds different to another. Filter Key Follow - Anti clockwise = negative, Middle = 0, Clockwise = positive. This gives the sound more 'liveliness'. The original TB-303 does not have this feature. LFO -> PW - Transistor Bass features one single LFO hardwired to the Pulse Width of the Pulse oscillator. This parameter determines how much the LFO influences the Pulse Width. LFO Rate - How fast the PW --> LFO oscillates PW - Absolute Pulse Width of the Pulse oscillator. NOTE: In the real 303 this is hardwired to about 66%. VCA Smooth - Turning this clockwise gradually removes attack and release clicks from notes. For the original 303 sound turn fully anti clockwise.

- These controls influence the oscillator. Distortion - The distortion is a simulation of the Pro Co Rat guitar pedal, as used by the legendary German acid techno duo "Hardfloor" (Ramon Zenker & Oliver Bondzio). Distortion Switch - Active/Deactivate the Distortion module. HP - Pre-distortion highpass. Drive - Distortion drive. Tone - Adjusts brightness of distorted sound is, basically a post-distortion lowpass. Output Volume - Adjust output volume of distortion circuit.

Delay - A simple delay that is not affected by pitch-warp effects when changing time on-the-fly. Delay Switch - Active/Deactivate the Delay module. Amount - Input send amount, similar to a "Wet" parameter. Time - Left speaker's delay time Right Tap - Right speaker's delay time (relative to left speaker's delay time) Feedback - Delay feedback (the number of echoes). Tone - Anti clockwise = Lowpass, Middle = Filter OFF, Clockwise = Highpass Stereo - Stereo Width BPM Sync - BPM sync for delay.

- A simple delay that is not affected by pitch-warp effects when changing time on-the-fly. Reverb - Based on FL Reeverb 2 with the addition of a Predelay Feedback . All other parameters are like in FL Reeverb 2. Low Cut - Low cut-off frequency. Use to removes low frequencies from the reverberations. Using the L.Cut parameter will reduce the 'rumble' and muddiness from the bass drum by attenuating the bass frequencies before being passed to the reverb engine. High Cut - High cut-off frequency. Use this to remove high frequencies from the reverb, or to make the room sound duller. Predelay - The delay time between the direct input signal and the first reverb reflection. Predelay should be set to modest values for small rooms, and can be increased to suit room size. Predelay creates a slap-back echo effect that can add atmosphere and muffle the signal, so use it wisely. Predelay FB - Predelay Feedback causes the Predelay to feedback just like a normal delay. Size - Room Size sets the size of the virtual room. For realistic effects, the Room Size should be adjusted according to the decay time. Small rooms sound better with a short decay time, large rooms sound better with longer reverb times. Diffusion - Density (spacing/number) of the reflections bouncing off the walls of the virtual room. A low diffusion setting makes the reflections sound more distinct and sparse, like closely spaced echoes. A high diffusion setting creates a dense series of reflections, so close they sound more like a constant decaying noise. Decay - Decay time of the reverb, this is the time it takes for the signal to decay to -60dB (1/1000 of the maximum amplitude). Use low decay times for small rooms (good for fattening drum sounds), and long decay times for large rooms (halls or church-effects). High Damping - High frequency decay in the reverb signal. This effect causes the sound to become gradually muffled and warmer. Dry - The relative level of the (dry) input signal passed to the outputs. ER (Early Reflection) - Sets the relative level of the first reflections in the reverb. Wet (Wet Level) - Sets the relative level of the reverberant (wet) signal. When using Reeverb 2 in a Send Channel this should be set to 100% (maximum).

- Based on FL Reeverb 2 with the addition of a . All other parameters are like in FL Reeverb 2. Sequencer The sequencer is 16 steps (1/16th notes). Transposing the sequencer from the Piano roll - Notes played on MIDI Channel 13, Note color 13 will transpose the sequencer up or down relative to the original C5 (MIDI note 60) pitch. You can trigger the sequencer via the Play/Pause button or via MIDI notes. Naturally it always plays the Sequence associated with the Program and note (up to 128 sequences can be saved). TIP: Rotate notes in Stepsequencer with (Shift+Ctrl+Arrows) Sequencer Controls Sequencer - When selected the internal sequencer will play based on input note. When deselected you can use the Piano roll & controllers as normal to play notes.
