Random Touches, Mixed and Spliced
Beltower can make random touch calls, from a selected subset of calls and/or plain leads. You can have mostly Bobs, Singles or plain leads, fewer of some, or none at all. You can also ring random Mixed and Spliced from a selected set of methods.
Manually Calling Touches and Call Changes
You can call your own call changes or Beltower can call random call changes, in addition to the pre-selected changes from the Call Changes Editor.
You can call your own touches, including spliced, and Beltower will remember the calling, so that you can review and/or edit it - handy when it doesn't turn out as planned. You can also start a touch from call changes (manual, random or pre-selected) or you can start ringing part way through an existing touch.
You can choose when to enter your calls: either at (or about) the selected voiced call time or up to a whole lead before.
Calls can be voiced between 280% and 127% of a stroke before they take effect. This allows calls to be timed at pull time 2 blows before, for use with tower bells, through to just before the lead strike 1 blow before, for hand bells.
In addition, with careful timing, you can call a method splice at any row, hand or back stroke.
External Sensors and Free Striking (silent practice) mode
You can input from sensors (dummy hand bells or tower bells) on any or all of the bells, or from a MIDI keyboard or other instrument, sounding the bells through your loud-speakers.
COM Port Input: Set-up is simple, allowing selection of input mode, ports, pins, debounce time, bells, delays, switches, calls, bell/call re-assignment and more, all through a single dialog box. Sensors should, normally, send short signals via either a timer interface or a serial interface box. Signals applied to individual pins on the COM ports can be detected, and with the Act-on-Pin High option, on either of the rising or falling edges. The High/Low Transitions option allows absolute control over hand and back stroke inputs, as each pin goes high or low, and the Act on Pin High option will determine hand or back strokes. Up to 32 inputs are available (4 pins on each of up to 8 COM ports) including USB to COM (RS232) converters.
USB Input: Besides the USB to COM converters, dummy hand bells are also available for USB via Graham John's Handbell Manager interface software. Buttons on the controllers can be used to start/stop, and call Go, Bobs etc. complete with Look To and Stand.
Advanced Features for Sensors:
Beltower provides an option to automatically call Go after a selected number of strokes.
Co-operative Timing allows the simulator to fit in with the real ringer(s), waiting if late or closing the gap if early, and can be used in a variety ways:
