Strobe tuner3/4/2023 Pitch Spectrogram plus Chord Matrix for transcription work).ĭictionary is a free offline English dictionary containing over 200,000 words and definitions and no ads. Split Screen (upgrade): Split the screen and use any two tuning views at the same time (e.g. Strobe Tuner (upgrade): A true 6-band, multi-mode strobe display for rapid and extremely accurate hands-free instrument tuning. Tone Generator (upgrade): An 8-octave, polyphonic keyboard display that enables you to play reference notes in the musical scale. Pitch Spectrogram (upgrade): Scrolling display of live sound analysis, showing the perceived pitch of a wide range of sound types. Stage Tuner: A large, clear tuning display, optimized for hands-free operation at a distance and incorporating a true radial strobe for unbeatable fine-tuning accuracy and responsiveness.Ĭhord Matrix (upgrade): Grid-based estimation display of common chord types (maj/min, maj7/min7, dom7/dim7), ideal for quickly determining the 'strum along' chords for a tune where the chords are reasonably clear. Includes standard Guitar tuning for free with a custom tuning editor and database of common tunings for Guitar, Violin/Fiddle, Mandolin, Ukulele, Banjo, Bouzouki and Pedal Steel available as an upgrade. Instrument: Combination chromatic ribbon tuner and string/note display for easy instrument tuning. Unique features help you work out the chords to new tunes, visualize the pitch and consistency of the human voice, violin or other instrument, or answer the questions "what notes am I humming", "what are those chords", "am I hitting all the notes in tune", "is my vibrato consistent" etc. I'd hold the test until I got some protection in place if I were you, but maybe you like toast better than me.Awesome guitar & chromatic tuner for free or upgrade for advanced functionality.ĭesigned for novices and pros, fully featured, easy to use. I've seen poor design before, and I would've put a zener across their power supply if this thing turns out to work at all.Įdit: the 470 ohm resistor will drop sufficient voltage at only 9mA total, and each IC draws an average of at least 10mA, so that's the explanation why it lasts. I doubt any other version or type would stand 25V (for very long). If you Google the IC and take a look at a pdf datasheet you'll see an image of the IC. If you connected those caps to ground or in parallell it could explain the overload. The resulting total capacitance is thus half of each section (5 uF) and it also becomes a bipolar capacitor (meaning it can stand Alternating Current). That makes it a series connection of the two 10uF caps. In the diagram the wires are only connected to the upper two terminals, nothing to the common terminal. If you disconnected the ground wire and measured infinite resistances to the frame then that (together with the other equal resistances) is a good sign that the motor is ok. i'd like to be able to confirm if the motor is alive or dead if anyone has any tips for that, or any other reccomendations. In any case, if anyone could point me in a good direction that would be great. i don't really know what it should look like or if it could be frying transistors. on the scope the signal looks like a spike up and then down. The other thing i'm not sure about is the signal coming in from the tuning circuit. however bot coils are not open and have the same inductance so i'm not certain how to confirm that its dead. What i'm considering now is either that the motor is dead. with the motor board removed everything is stable and seems good. i can't really make any voltage reading on the motor board because it seems like it would start a small fire. everything else on that board seems to be just fine (although i'm not too sure about how to test the flipflops properly but all three share the same resistance readings). tried replacing them but they just toasted again. the MJE711 was burnt out and the 3.3ohm resistors were testing high. Naturally i began looking at the motor control board. the motor lookls like its trying to turn over but just moves about a quarter inch but does not spin. the strobe lights are on and respond to an input. the power supply seems to be giving the right voltages. here's whats going on and what i know.Įverything seems to work except the motor. i'm trying to get a broken peterson strobe tuner model 400 working again and have hit a bit of a wall.
