<div dir="ltr">I'd expect that lowest note is going to vary by manufacturer to manufacturer. You'd hope that professional digital organs from Viscount or Crumar or anyone else would allow you to transpose those before sending it out, but I'm sure there are many retrofitted organs or less comprehensive ones that can't be adjusted. <div><br></div><div>I would include a transpose feature on the sound module to accommodate all key range circumstances. That way you just need to make sure it works by default with whatever is most popular and leave the rest of the work up to users :)</div><div><br></div><div>Nathan</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Sat, Feb 10, 2024 at 5:04 PM Jean-Pierre Desrochers <<a href="mailto:jpdesroc@oricom.ca">jpdesroc@oricom.ca</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div class="msg3032261391759035142"><div lang="FR-CA" style="overflow-wrap: break-word;"><div class="m_3032261391759035142WordSection1"><p class="MsoNormal"><span>To make it clearer I’m working on a MIDI module that will produce<u></u><u></u></span></p><p class="MsoNormal"><span>Pipe organ pipe sounds from incoming MIDI notes from a separate pedal MIDI controller.<u></u><u></u></span></p><p class="MsoNormal"><span>My pedal board starts with the lowest C note value of 36 deci (0x24).<u></u><u></u></span></p><p class="MsoNormal"><span>This module will itself generate (selected tabs on the unit)<u></u><u></u></span></p><p class="MsoNormal"><span>6 separate and mixable 1, 2, 4, 8, 16, 32 foot pipe lengths sounds (6 separate oscillators).<br>So an incoming MIDI note will trigger the pipe organ sound<u></u><u></u></span></p><p class="MsoNormal"><span>But the MIDI note itself will not decide ‘which’ stops have been selected on the unit.<u></u><u></u></span></p><p class="MsoNormal"><span>So..
