• Welcome to the Pipe Organ Forum! This is a part of the open community Magle International Music Forums focused on pipe organs (also known as "church organs"), organists, organ music and related topics.

    This forum is intended to be a friendly place where technically advanced organists and beginners (or even non-organists) can feel comfortable having discussions and asking questions. We learn by reading and asking questions, and it is hoped that the beginners (or non-organists) will feel free to ask even the simplest questions, and that the more advanced organists will patiently answer these questions. On the other hand, we encourage complex, technical discussions of technique, music, organ-building, etc. The opinions and observations of a diverse group of people from around the world should prove to be interesting and stimulating to all of us.

    As pipe organ discussions can sometimes become lively, it should be pointed out that this is an open forum. Statements made here are the opinion of the poster, and not necessarily that of the forum itself, its administrator, or its moderators.

    In order to post a new topic - or reply to existing ones - you may join and become a member by clicking on Register New User.

We strive to make this a friendly and informative forum for anyone interested in pipe organs and organ music.

Johannus Intonat software


New member
I have been using Intonat 97 v 3.2 to work with my Johannus Opus 10 AGO/USA. I find that it works extremely well. I have an old IBM ThinkPad 240 running Windows 98 that does nothing but sit near the organ when I want to tweak something. It is extremely easy to use, and comprehensive.

[Edit] All the adjustments below except the Default reload are separate for each intonation. I must change a stop note volume separately for romantic and baroque. To me this makes sense.

With it I can
- change the volume of each note of each stop of each intonation (romantic, baroque)
- change the windsag for each division
- change the depth of the tremulant for each stop of each intonation
- change the speed of the tremulant for each division
- change some of the speech characteristics using Treble and Bass controls, like on an amplifier
- save files on the computer and recall them. This feature allows me to save a custom set for specific music. I could increase the relative volume and treble of the reeds (and detune them slightly) for French music. Loading this file does not modify the organ settings permanently.
- The organ (and remember that this is 1997 design) has three memories for the intonations:
- ROM. Going back to the factory settings is a couple of mouse clicks to reset the next memory to the factory settings.
- FLASH. the settings as modified by you that you saved to the organ as the default voicing when it boots up.
- RAM. the settings in use at the moment. These can be the temporary adjustments from the FLASH memory. Until you Save the organ can be reset to your preferences by turning it off and on again.
- Save is intonation by intonation: I can modify the baroque and leave the romantic alone, except for the >Organ >Default mouse clicks that reload the whole factory standard.

I am certain that the newer versions can do much more because the organs are capable of much more than my 1997 designed instrument.
