Bass Line – User’s Manual 

 

 

Control Section 

The control section is used to specify how ABL should operate.  
 

 

Midi Led 

The Midi Led will light when there is Midi activity sent to the plug-in. The plug-in 
receives Midi information on all 16 channels. 

Sync 

The sync mode switch has two settings: Internal and Host. To change the settings click 
on the switch and slide the mouse in the direction you wish to set the switch. 

 

In Internal sync mode it is possible to set the tempo between 50 and 250 BPM  

 

In Host sync mode the tempo control has no effect as the tempo is read from the 
host, and cannot be altered from ABL.  

Mode

 

The Midi Mode switch operates as the Sync switch. The two settings are: 

 

PTN - Patterns are selected from Midi notes. Each Midi note corresponds to one 
pattern, with the lowest possible note being pattern 0 (zero) and the highest note 
pattern 127. A note on message will start a pattern and a note off message will 
stop the pattern. 

 

NOTE - Notes are played directly from the Midi notes and the internal sequencer 
is disabled. This allows ABL to be played as normal synthesizer. If two notes 
overlap then a slide will occur between those notes. If a note with velocity over 
100 (default) is played then an accent will be activated. 

Option  

The option menu is activated by clicking on the text or near the arrow. This menu allows 
you to alter the way ABL functions. 
 

Midi CC  

Activate Midi learn 

Selecting this item will activate Midi learn and change the 
item to Deactivate Midi learn

 

Emulation 

Switch to 24dB filter 

The filter can be switched to 24dB/octave attenuation. 
The number denotes the slope of the filter cutoff in 
decibels per octave. The 18dB/octave filter (modeled 
after the original Bass Line) has a brighter sound than 
the 24dB filter.  

Switch to non-exact tuning  Switching to non-exact tuning makes the oscillator out
