OSC start by visiting opensoundcontrol org Two settings control what port the plug in uses to listen on for OSC com mands One is the base OSC port set in the preferences The second is the OSC Port Offset control If the port offset is set to something other than Off then the two numbers are added together and the result used as the port number E g if the base port is 6000 and the port offset is 1 then the plug in will listen on port 6001 Reference All Expert Sleepers plug ins that support OSC share a common implementation This is documented in the OSC Control Manual available from the Expert Sleepers website MIDI amp OSC Scripting It is possible to extend the plug in s MIDI amp OSC functionality via user writeable scripts Indeed the standard MIDI functionality described above has been re implemented using such a script which you can use as reference for your customisations The language used for the MIDI scripts is Lua You will find a complete description of the language and some useful tutorials at the Lua website www lua org All the standard language features of Lua are available in the scripts plus some extra func tions specific to the Expert Sleepers system Reference All Expert Sleepers plug ins that support MIDI OSC scripting share a common implemen tation This is documented in a the MIDI amp OSC Scripting Manual available from the Expert Sleepers website Script locations

Hz useful for audio rate modulation sound effects Speed LFO The Speed LFO modulates the Speed value set above It has simple speed and depth controls Depth The 2 depth knobs together set the main LFO depth Their values are simply added The readout above the knobs shows the current depth setting currently being used NB this also takes into account the effect of the Depth LFO see below Note that while the depth knobs are calibrated in percent the depth readout shows a value in milliseconds Also note that the depth readout value is affected by the current speed value The reason it works this way is that the pitch modulation you hear is dependent on both the delay time the depth in ms and the speed By having the depth knob control not the de lay time but the actual pitch modulation depth it is much easier to set a modulation amount you like and then change the speed of it For example if you set the depth to 100 and the LFO shape to square you ll hear a sound that exactly cuts out for one half of the LFO waveform Now vary the speed and you ll hear the same effect just getting faster or slower even though the depth readout shows the depth in ms varying with the speed The above is not really important to understand just using your ears and finding an effect you like is usually the best policy but I mention it just to explain a little the philosophy of this control method which might seem odd to those
7. It amounts to different typical delay times 20 30ms for chorus vs 1 10ms for flange and flange having a feedback path Warbler offers delay times from below 1ms to more than 1s and offers feedback so clearly can offer a wider range of effects than is usual for a simple chorus flange Delay effects By raising the bias control and using the coarse depth control with a lowish speed setting you can select delay times more commonly associated with delay effects than with a cho rus up to over 1 second Use the feedback control for repeating echoes When you combine this with the depth and speed LFOs and use bias settings that are somewhere between 0 0 and 1 0 you can get very complex effects sort of modulated vi brato chorusy delays Extreme sound mangling Use the coarse speed control to select audio frequency LFO modulation You ll also need to crank up the coarse depth control to hear an effect Using these settings you can easily get some weird ring modulation like sounds that are especially useful on drum or other non pitched parts The controls in depth Speed The 3 speed knobs together set the main LFO speed Their values are simply added The readout above the knobs shows the current speed value being used NB this also takes into account the Speed LFO see below The knob ranges are e Superfine 0 1Hz useful for very slow modulations e Fine 0 5 20Hz useful for normal vibrato effects e Coarse 10 5000

12. ll spread values on e g a Sine waveform give the subtle thickening just mentioned You can also use more extreme settings e g a spread of 0 5 on a Square waveform causes the two stereo channels to mirror each other s pitch Chorus Flange The Bias control fundamentally reconfigures the effect from being a vibrato to being a traditional modulated delay line chorus flange It does this continuously however so there is a huge range of possi bilities between the two extremes When bias is set to 1 0 i e it s in chorus flange mode using the Depth LFO to modulate the depth often sounds good The Feedback knob introduces feedback into the delay line This is commonly used in flange effects to create a more resonant sound Note that you can use this control regard less of the setting of bias even when the plug in is in pure vibrato mode Negative values of feedback give phase inverted feedback in the delay line It just sounds a bit different Mix This section simply controls the level of the effected wet and uneffected dry signals For a vibrato you ll probably want the dry level at zero For a cho rus it s usual to mix the two signals Preferences Pressing the Prefs button brings up a dialog where various prefer ences are set These settings are shared by all instances of Warbler and are not stored with presets The top section shows the product ver sion The cen
