TimeFactor Self Oscillation Drone
Background information:
This is a drone created with an Eventide TimeFactor and a Roland SRV-3030. Sound was generated by the TimeFactor’s self oscillation – nothing was plugged into the input. The output of the first delay unit was connected to the second, and mono output of the second was connected to the A input of the SRV-3030. All adjustments were performed live by hand.
Hardware feature:
The SRV3030 is a smartly styled 1U processor with stereo analogue I/O on both balanced jacks and XLRs. MIDI In and Out/Thru sockets are fitted, and on the the SRV3030D model only, there is digital S/PDIF I/O on phono connectors (but no AES-EBU on XLRs). Control jacks are available for an optional footswitch (bypass) and an expression pedal for controlling input level.
Though the SRV3030 is a highly sophisticated digital reverb unit, the front-panel controls are mercifully few and are mainly dedicated to single tasks rather than being multi-function. The display makes use of instrument icons to show what category a reverb belongs to, and all the editable parameters may be accessed as a single list — there are no forking menus.
At the heart of the SRV3030 are two reverb processors, A and B. These may be used separately as mono in, stereo out processors, or combined in series or parallel. In addition, there’s a pre-reverb compressor within the normal reverb algorithm, plus two further processing blocks, one for the RSS stereo width expansion (based on the algorithms used in Roland’s dedicated RSS 3D sound processor) and an effects block based on modulated delay effects. The effects block may be placed after either or both reverb blocks but, oddly, it can’t be positioned before the reverb input to add ‘spin’ or ‘swirl’ to the reverb.
