What is Music
At your risk.
Beautiful playing game, interaction between the bass melody and the melody in our mind.
For example:
Largo from Bach F minor Concerto.
Just 2 melodies creating beautiful intervals of 2 notes are sounding together.
Curing a cat with kidney problems?
At your risk.
This is not a medical advice or a nutritionist advice.
Using the freshest possible fish? boiled with just filtered? water, no oil no salt?
The Pleiades amplifier model numbers can be really the schematic
At your risk.
For example Pleiades K117 220R 4M7.
See previous post.
How to connect a Sennheiser MD421HN to iPhone for recording with Garageband, or camera etc.
At your risk.
The beautiful microphone can be 24in away with no need to set the bass correcting switch for proximity effect. Recording outdoors with windshield will avoid close wall reflections.
The MD421HN already has an internal step up transformer, so no need to add an external.
So the impedance is high, the voltage high and we are ready to connect to the gate of a JFET.
For example the Pleiades K117 220R 5M5 preamplifier can be used. The JFET is a K117, a 220ohm resistor is used connected between the source terminal of the JFET and ground, and a 5.5Megohm between gate and ground. Then the drain terminal is connected to the mic input of the mobile device iPad or iPhone. For a modern device an apple USB C to 3.5mm adaptor is used, See previous posts. Headphones may need to be connected so that the mic is recognized too.
The MD412HN high Z signal is connected to the gate of the JFET and the whole Pleiades preamplifier can be assembled inside the mini Tuchel connector as it is only a JFET and 2 small resistors.
It sounds very nice with no hiss or noise.
Garageband
At your risk.
It looks very promising. The fantastic sound of strings expression modulated by hand touching the iPad iPhone screen.
Trying to persuade Zhanna to use. I think she really appreciated the sound and she played something so beautiful using the cinematic strings.
How about trying to making it do more things.
For example:
Recording the upper strings playing C major but then adding cello and double bass playing E instead of C.
Using 2 devices so that one person can play melody at the piano and the other the bass part at the piano, thereby expanding the keyboard and recording 2 persons playing live.
Adding an Apple USB C adaptor to 3.5mm and connecting a Pleiades K117 microphone single JFET preamplifier so that a studio microphone can be connected such as Sennheiser MD421, see next post.
Recording with windshield outdoors so that acoustics are infinite, very high reverberation radius.
